A coalgebraic treatment of conditional transition systems with upgrades
We consider conditional transition systems, that model software product lines with upgrades, in a coalgebraic setting. By using Birkhoff's duality for distributive lattices, we derive two equivalent Kleisli categories in which these coalgebras live: Kleisli categories based on the reader and on the so-called lattice monad over Poset. We study two different functors describing the branching type of the coalgebra and investigate the resulting behavioural equivalence. Furthermore we show how an existing algorithm for coalgebra minimisation can be instantiated to derive behavioural equivalences in this setting
Frontiers of open quantum system dynamics
We briefly examine recent developments in the field of open quantum system
theory, devoted to the introduction of a satisfactory notion of memory for a
quantum dynamics. In particular, we will consider a possible formalization of
the notion of non-Markovian dynamics, as well as the construction of quantum
evolution equations featuring a memory kernel. Connections will be drawn to the
corresponding notions in the framework of classical stochastic processes, thus
pointing to the key differences between a quantum and classical formalization
of the notion of memory effects.Comment: 15 pages, contribution to "Quantum Physics and Geometry", Lecture

Am deutschen Vorbild orientiert: Europäische Mitbestimmung
Die Arbeitnehmerbeteiligung ist in Europa aus unterschiedlichen Elementen geformt. Bei den einen gibt es mehr Streikrechte, dafür aber weniger Aufsichtsratssitze. Oder umgekehrt. Von daher ist die deutsche Mitbestimmung nicht einzigartig stark. Sie ist unser spezifisch deutscher Pfad
