Self-adjoint

（重定向自Self adjoint）

In mathematics, an element x of a *-algebra is self-adjoint if $x^{*}=x$ .

A collection C of elements of a star-algebra is self-adjoint if it is closed under the involution operation. For example, if $x^{*}=y$ then since $y^{*}=x^{**}=x$ in a star-algebra, the set {x,y} is a self-adjoint set even though x and y need not be self-adjoint elements.
