摘要
A numerical index is introduced for semigroups of completely positive maps of B(H) which generalizes the index of E-0-semigroups. It is shown that the index of a unital completely positive semigroup agrees with the index of its dilation to an E-0-semigroup, provided that the dilation is minimal. (C) 1997 Academic Press.
