초록

The aim of this paper is to find the set of the fixed elements and the set of elements for which equality holds in Schwarz inequality for the KMS-symmetric Markovian semigroup {S_t}_{t≥0} given in [10]. As an application, we study some properties such as the ergodicity and the asymptotic behavior of the semigroup.

Abstract

The aim of this paper is to find the set of the fixed elements and the set of elements for which equality holds in Schwarz inequality for the KMS-symmetric Markovian semigroup {S_t}_{t≥0} given in [10]. As an application, we study some properties such as the ergodicity and the asymptotic behavior of the semigroup.
