Direct Products of Groups  (Abstract Algebra)
 
08:55
The direct product is a way to combine two groups into a new, larger group. Just as you can factor integers into prime numbers, you can break apart some groups into a direct product of simpler groups.

Matrix Groups  (Abstract Algebra)
 
04:16
Matrices are a great example of infinite, nonabelian groups. Here we introduce matrix groups with an emphasis on the general linear group and special linear group. The general linear group is written as GLn(F), where F is the field used for the matrix elements. The most common examples are GLn(R) and GLn(C). Similarly, the special linear group is written as SLn.

Graph Theory: 49. Cartesian Product of Graphs

What is the Cartesian product of two graphs? We start with a reminder of what this means just for sets and then provide the formal definition for graphs. We include a few examples to become familiar with the idea and we also briefly discuss what a hypercube (or n-cube) is in graph theory. -- Bits of Graph Theory by Dr. Sarada Herke.

Use this site and adjust the sliders - http://www.infinitelooper.com/ The 6-minute hypnosis at the start (STAGE #1) is there to help you fall asleep within the first 10-minutes of the lucid dream inducement (STAGE #2). It's therefore recommended that you listen to STAGE #1 before every session until you're confident that you can fall asleep without it, in which case just click on the annotation at the start to skip straight to the induction. The reason you have to sleep within 10 mins of STAGE #2 is so that the peak of your REM sleep/dream activity syncronizes with the triggers/affirmations at 1:11:28 secs. STAGE #1 has the added benefit of providing several affirmations to prepare your mind for lucidity; "Tonight I will lucid dream", "I am the master of my dreams" etc. (see below) The first 65 minutes of STAGE #2 will guide your brainwaves into a deep Delta sleep, while the remainder will transition your mind into Theta, the state in which REM sleep and dreams (at their peak intensity) occur. From 65 mins of Stage #2 onwards, there will be a number of affirmations designed to trigger lucidity. You are advised to skip to these now so that you can adjust volume levels accordingly. (1:11:28 secs ) It is important to develop the habit of performing 'reality checks' throughout the day as the affirmations will prompt you to perform these in your dream. Of course you may even trigger lucidity without this audio - but this is just a tool to help you speed up the process. The key to getting results is persistence. ------------------------------------ STAGE #1 AFFIRMATIONS (before and after the relaxation hypnosis) ------------------------------------ "The next time I am dreaming, I will know that I am dreaming "I am the master of my dreams" "Tonight I will have a lucid dream" "When dreaming, I recognize that I am dreaming" ------------------------------------ STAGE #2 AFFIRMATIONS (From 1Hr 11 Mins 28 secs onwards) ------------------------------------ "You are dreaming" "Do a reality check" "This is a dream" "You are taking control of your dream" "You are now dreaming" "Is this a dream?" "Perform a reality check" "I am awakening within my dream" "I am becoming consciously aware" 90 minute sleep cycle Lucid Dream Music: https://www.youtube.com/watch?v=yRyDqwmnLAM

Matrix Band - Precontour Interproximal Region - Complex Direct Restorations
 
07:51
This little tip may play a huge role when placing large, complex restorations (amalgam and composite). Preburnish the interproximal regions of your metal matrix band to obtain a better contact and gingival health - and decrease the likely hood of food impaction from the buccal and lingual. Of course, if contours and contacts are a huge issue - a full coverage restoration (indirect), will hopefully solve those problems. This was a great tip that I read about in Sturdevant's and Summit's textbooks - later shown to me by Dr. Queso. (Thanks Ryan). www.allthingsdentistry.com www.dentistrylearningnetwork.com This tooth is a part of a demonstration of complex amalgam restorations. The pins are controversial, however, a discussion regarding complex amalgam restorations is not complete without bonding, slots, grooves and pins. More to follow!

Easy Trick To Multiply Matrices Cool Shortcut Matrix Precalculus discrete
 
11:40
For more cool math videos visit my site at http://mathgotserved.com or http://youtube.com/mathsgotserved Multiplicación de Matrices 3x3 Good day students in this clip were going to be going over an easy trick or method for multiply matrices in the forget to go to mathgotserved.com of to see what collection of great math tutorials. Right let's take a look at the first example of problem number one is a were to find of the product of these two matrices two one four five are multiplied by three two five one okay let's a were to find the product is to matrices of course the product of matrices are not always defined so for so we have to determine if the product is defined that can be done by looking at the dimension of a matrices this has to Rosen to: so this is the two by two oh in neuritis in the bottom so this is a two by two matrix and this matrix right here the two by two matrix now how do we know if the of product is the find what we do is we look at the column of the first of the of the called with the call this the multiply matrix multiplier in then we can call that the multiply can't matrix okay right so we look at the column of the multiply matrix and the role of the multiply can matrix and what ask ourselves are these two numbers the same as is number and is number our data same in the answer is yes so said it equal that we can multiply them okay. The product is the find what is the dimensions of the product going to be to determine that you look at the role of the multiply matrix and that on the of column of the multiply can matrix and that will be the dimensions of our product so we should expect to get it to by two matrix as the final result right now since is determined that the product of these matrices us to find of let's go ahead and use of the trick I was going to show you so why is it important why am I doing this tutorial make sure you this trick well multiply matrices is not that difficult, but the process can get cluttered okay and when you have quadrant the workspace is very easy to make little arithmetic errors with Joseph your answer is with the have blanketed I flex eight on we could start to invert numbers and make us to the mistakes so the definitely pain that's why of abolishing this method okay so what you going to do is you going to basically of set up your product in such a way that it's very difficult to make mistakes always been is basically saying us also for success okay so I'm going to take the multiply the way that you multiply matrix and angle with that first before I see how to do this is you multiply the role in in the multiply matrix by the column of of the multiply can matrix okay you multiply like this and then you do that and then you do this any go to bottom and that embodiment in this again the cube enrolled has caller times column and that's how you get your answer. So that rotation back-and-forth between rows and columns the multiply matrix and the multiply can matrix is a lot of room for mistakes and disorganization okay so that's why, one issue disclosure it so just remember that you multiply the Rose of the first to multiply matrix with the column of the multiply can the second matrix okay now, with that in mind with me show you how to set this up what you do is you take the Rose and the multiply multiply matrix and my demise coordinates okay this is the time to buy to so let's write it as a of X to the massacre next to life's is to, for for the first wrote it to come of four and then for the second row one, five so into dimensions you can think of this is X Y X Y right now this is the co-part of will going to write down the columns in the multiplicand matrix in a horizontal orientation right so three two is the column in in in the second matrix right here. So write it as three, two right and then five one I'm going to oriented in a horizontal fashion five, one right to is go over this again to multiply arose that the Rosen the multiply matrix right him just as is, but the columns in the multiply can matrix the second matrix and multiply by you just oriented horizontally okay right now that I have a set up like this is such as this cake of from here on out so what were going to do is basically multiply the numbers by multiplying I'm corresponding coordinates okay so excess times X Y can't why and you find the Psalm of the products okay so for this of coordinate and that coordinate doesn't going to the first entry two times three is six plus four times two eight okay what six is eight fourteen so that the first entry in our resultant matrix of mining the one times three three plus four times to ten three percent thirteen right, one and then if two times five multiply the X is ten plus the wise four times one for added of fourteen okay and then the next one we have one times five five plus one times five five of them together get ten so your our final matrix the product of this to matrices is fourteen fourteen thirteen and ten right so

Linear Algebra is one of the most important subjects in mathematics. It is a subject with boundless practical and conceptual applications. Linear Algebra is the fabric by which the worlds of geometry and algebra are united at the most profound level and through which these two mathematical worlds make each other far more powerful than they ever were individually. Virtually all subsequent subjects, including applied mathematics, physics, and all forms of engineering, are deeply rooted in Linear Algebra and cannot be understood without a thorough understanding of Linear Algebra. Linear Algebra provides the framework and the language for expressing the most fundamental relationships in virtually all subjects. This collection of videos is meant as a stand along self-contained course. There are no prerequisites. Our focus is on depth, understanding and applications. Our innovative approach emphasizes the geometric and algorithmic perspective and was designed to be fun and accessible for learners of all levels. Numerous exercises will be provided via the Lemma system (under development) We will cover the following topics: Vectors Linear combinations Decomposition Linear independence Null space Span Linear systems Gaussian elimination Matrix multiplication and matrix algebra The inverse of a matrix Elementary matrices LU decomposition LDU decomposition Linear transformations Determinants Cofactors Eigenvalues Eigenvectors Eigenvalue decomposition (also known as the spectral decomposition) Inner product (also known as the scalar product and dot product) Self-adjoint matrices Symmetric matrices Positive definite matrices Cholesky decomposition Gram-Schmidt orthogonalization QR decomposition Elements of numerical linear algebra I’m Pavel Grinfeld.

PCPs of Sub-Constant Error Via Derandomized Direct Product - Or Meir
 
01:17:19
PCPs of Sub-Constant Error Via Derandomized Direct Product - Or Meir The Weizmann Institute of Science October 19, 2009 A PCP is a proof system in which the proofs that can be verified by a verifier that reads only a very small part of the proof. One line of research concerning PCPs is trying to reduce their soundness error (i.e., the probability of accepting false claims) as much as possible. In particular, using low-degree curves, it is possible to construct PCP verifiers that use only two queries and have soundness error that is an inverse poly-logarithmic function in the input length. In this talk, we show a an alternative construction of such PCPs, using a simpler and less algebraic approach. This is done by extending the derandomized direct product test of Impagliazzo, Kabanets and Wigderson (STOC 09) to a construction of a PCP. To that end, we identify general properties of a PCP that allow amplifying its soundness by the means of direct product. We then show that any PCP can be transformed into one that achieves those general properties by embedding the corresponding constraint graph on a de-Bruijn graph. No prior knowledge of PCPs will be assumed. (This is joint work with Irit Dinur.) For more videos, visit http://video.ias.edu

AlgTopReview4: Free abelian groups and non-commutative groups
 
50:59
Free abelian groups play an important role in algebraic topology. These are groups modelled on the additive group of integers Z, and their theory is analogous to the theory of vector spaces. We state the Fundamental Theorem of Finitely Generated Commutative Groups, which says that any such group is a direct sum of a finite number of Z (integers) together with a finite commutative group (the torsions part). Non-commutative groups are also briefly introduced, mostly through the simplest example of S_3, the symmetric group on three objects, or alternatively the group of 3x3 permutation matrices. We illustrate that cosets of a subgroup in the commutative case are of two different types: left and right, and this makes the situation more complicated. When the left and right cosets agree we are in the situation of a normal group, and then the cosets do form a quotient group. Thanks to Nguyen Le for filming.
