摘要

For an automorphism alpha of a unital C*-algebra A, we give a definition of an entropy ht(phi)(alpha) with respect to an alpha-invariant state phi of A. For Connes-Narnhofer-Thirring entropy h(phi)(alpha) and Voiculescu's topological entropy ht(alpha), in general h(phi)(alpha) less than or equal to ht(phi)(alpha) less than or equal to ht(alpha), but the equalities do not always hold. We compute entropies of an endomorphism p with respect to the state phi defined from a left inverse of p. Cuntz's canonical inner endomorphism Phi of O-n satisfies h(phi)(Phi) = ht(phi)(Phi), which is determined by the mean entropy of phi on the UHF (uniformly hyperfinite) algebra. If gamma is Longo's canonical endomorphism for an irreducible graded standard AFD (approximately finite dimensional) inclusion N subset of M of infinite factors with finite index, then h(phi)(gamma) = (1/2) log(Ind E-gamma), for the conditional expectation E-gamma on gamma(M).
