essentially self adjoint operator
1.Error Estimate to the Simplified Iteration for the PositiveSemi-Definite,Compact and Self-Adjoint Operator Equation
3.This paper discusses mapping theorem of the Weyl limit points for a self--adjoint operator A:W(f(A) ) =f(W (A) ) , where f is the real continuolJS function defined by spectra o(A) of A and fi CIR (o(A) ).
4.Each observable is represented by a densely defined Hermitian (or self-adjoint) linear operator acting on the state space.
