Causal fermion systems and Lorentzian geometry
The theory of causal fermion systems is an approach to fundamental physics. It gives quantum mechanics, general relativity and quantum field theory as limiting cases and is therefore a candidate for a unified physical theory. The dynamics of causal fermion...

Conferencia Ángela Capel: When does a quantum many-body system mix rapidly?
A quantum memory can be described by the evolution of an open quantum many-body system in a thermal bath with which it weakly interacts, which can be modelled by a quantum Markov semigroup. The time that it takes for an initial state on the system to reach the...
An exploration of the size of chaotic phenomena for composition operators through lineability and spaceability. Martina Maiuriello (Università degli studi della Campania Luigi Vanvitelli).

Isomorphic copies of l_∞ in the weighted Hardy spaces on the unit disc. Radoslaw Szwedek, Adam Mickiewicz University, Poznan.
