... So I'm naturally going to call that the eigenvector matrix, because it's got the eigenvectors in its columns. And all I want to do is show you what happens when you multiply A times S. So A times S. So this is A times the matrix with the first eigenvector in its first column, the second eigenvector ...

Matrix Lie groups and their Lie algebras
... (c) The orthogonal group O(n): Recall that A ∈ O(n) if and only if AT A = I . Now let {Ak } be a sequence in O(n) such that Ak → A. Passing to limit in the equation ATk Ak = I gives that AT A = I ; that is, A ∈ O(n). (d) The special orthogonal group SO(n): The proof that SO(n) is a matrix Lie group ...

... trix addition (1), Let A = [aij ], B = [bij ]. Both A and B have same size m × n, so A + B, B + A are defined. From definition A + B = [aij ] + [bij ] = [aij + bij ] and B + A = [bij ] + [aij ] = [bij + aij ]. From commutative property of addition of real numbers, we have aij + bij = bij +aij . Ther ...

Characterizations of normal, hyponormal and EP operators
... denote the set of all linear bounded operators from H to K. The MoorePenrose inverse of A ∈ L(H, K) is denoted by A† (see [3], page 40). We use R(A) and N (A), respectively, to denote the range and the null-space of A ∈ L(H, K). For given A ∈ L(H, K) the operator A† ∈ L(K, H) exists if and only if R ...
