英英释义

  • In mathematics, especially functional analysis, a self-adjoint (or hermitian) element A of a C*-algebra \mathcal{A} is called positive if its spectrum \sigma(A) consists of non-negative real numbers. Moreover, an element A of a C*-algebra \mathcal{A} is positive if and only if there is some B in \mathcal{A} such that A = B^* B.
