Automatic time continuity of positive matrix and operator semigroups

Jochen GlÃ¼ck

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 GlÃ¼ck, 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…
