What can Koopmanism do for attractors in dynamical systems?
Viktoria Kühner
We characterize the longterm behavior of a semiflow on a compact space by asymptotic properties of the corresponding Koopman semigroup. In particular, we compare different conc…

Measure-preserving semiflows and one-parameter Koopman semigroups
Nikolai Edeko, Moritz Gerlach, Viktoria Kühner
We characterize Markov lattice semigroups induced by measurable semiflows on probability spaces by properties of their generators. In addition we construct topological models on co…
