From playlist Intro to Matrices
We have already looked at the column view of a matrix. In this video lecture I want to expand on this topic to show you that each matrix has a column space. If a matrix is part of a linear system then a linear combination of the columns creates a column space. The vector created by the

Definitions of matrix equality and matrix addition allow us to prove that there's a "zero" matrix: an m by n matrix Z that, when added to any other m by n matrix A, yields A. (We also show that Z is unique.)

Topics in Combinatorics lecture 10.5 --- An entropy proof of Brégman's theorem
The permanent of a square matrix is like the determinant except that you don't multiply by the signs of the permutations. Since the determinant arises very naturally, the "simpler" definition of the permanent actually leads to a quantity that is less natural and very hard to calculate. How
