Automatic time continuity of positive matrix and operator semigroups

Jochen Glück

We consider a matrix semigroup $T : [0, \infty) \to R^{d \times d}$ without assuming any measurability properties and show that, if $T$ is bounded close to $0$ and $T(t) \ge…

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…

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…
