Uniform ergodic theorems for semigroup representations

Jochen Glück, Patrick Hermle, Henrik Kreidler

We consider a bounded representation $T$ of a commutative semigroup $S$ on a Banach space and analyse the relation between three concepts: (i) properties of the unitary spectrum of…

A note on the positivity of inverse operators acting on $C^{*}$ -algebras

Jochen Glück, Ulrich Groh

For a positive and invertible linear operator $T$ acting on a $C^{*}$ -algebra, we give necessary and sufficient criteria for the inverse operator $T^{- 1}$ to be positive, too. Moreov…

Aperiodicity of positive operators that increase the support of functions

Jochen Glück

Consider a positive operator $T$ on an $L^{p}$ -space (or, more generally, a Banach lattice) which increases the support of functions in the sense that $s u pp (T f) \supseteq s u pp f$ fo…
