If there exists a self-adjoint operator A such that A Ç BC, where B and C are self-adjoint, then B and C strongly commute. ... Let A be an unbounded self-adjoint operator and let B and C be two closed symmetric operators such that AB C C. If B has a bounded inverse (hence it is self-adjoint), then C is self-adjoint.
Do self adjoint matrices commute?
Corollary: Any set of commuting self-adjoint matrices have a common set of eigenvectors. Proof: They all commute with one of them A, hence have the same eigenvectors.
Does an operator commute with its adjoint?
In mathematics, especially functional analysis, a normal operator on a complex Hilbert space H is a continuous linear operator N : H → H that commutes with its hermitian adjoint N*, that is: NN* = N*N.
