In this talk we will explore the following notions of chaos for operators on non-metrizable topological vector spaces: mixing, hypercyclicity, cyclicity, n-supercyclicity, Li-Yorke chaos and Devaney chaos. We will discuss the main differences between these...

In this talk, we introduce basic of local entropy theory and discuss how it can be applied in various settings in topological dynamics. We pay particular attention to Uniformly Positive Entropy and Complete Positive Entropy introduced by Blanchard in 90’s. Whereas...

We revisit some ideas of K.-M. Perfekt who has provided an elegantframework to detect the biduality between function or sequence spacesdefined in terms of some o-resp.O-condition. We present new proofsunder somewhat weaker assumptions than before and apply the result...

In this presentation we talk about our graph-based model for action spotting in soccer games. The goal of action spotting is to identify the specific time an action occurs. Our model represents players, referees, and goalkeepers as nodes in a graph and connects...
