Abstract

In this paper, we discuss about spectrum properties of self-adjoint operator. Relation between self-adjoint operator and normal operator is used to show that the spectrum of self-adjoint operator is subset of real numbers set. Furthermore, by using norm properties of bounded-linear operator and real polynomial we derived the relation between spectrum and norm of operator polynomial.

Keywords: spectrum, self-adjoint operator, normal operator
