Normal operator: Products, Properties & Properties in finite-dimensional case

In mathematics, especially functional analysis, a normal operator on a complex Hilbert space H {\displaystyle H} is a continuous linear operator N : H → H {\displaystyle N\colon H\rightarrow H} that commutes with its Hermitian adjoint N ∗ {\displaystyle N^{\ast }} , that is: N ∗ N = N N ∗ {\displaystyle N^{\ast }N=NN^{\ast }} .
