报告摘要:We study the completely positive maps defined on the Banach space of all bounded linear operators and its restriction to the Banach space of all compact operators. The relationship of the boundary eigenvalues and the spectra of these two class maps are established. In particular, the spectra of completely positive maps involving the unilateral shift are described.
