Honeycombs and sums of hermitian matrices

WebA Hermitian matrix is a matrix that is equal to its conjugate transpose. Mathematically, a Hermitian matrix is defined as A square matrix A = [a ij] n × n such that A* = A, where A* is the conjugate transpose of A; that is, if for every a ij ∊ A, a i j ― = a i j (1≤ i, j ≤ n), then A is called a Hermitian Matrix. WebIt remains to check that 1 2 ( A + A †) and 1 2 i ( A − A †) are Hermitian: take the Hermitian conjugate and see what happens. And even if you didn't think of that decomposition, you …
