Abstract

An infinite group G is said to have property Ro if every automorphism p e Aut(G) hasR(yp)= co where R(y) denotes the cardinality of the set of orbits of the (left) action of G on G viao. a +> aap(o)-1. The study of (in)finiteness of R(yp) has its origin in Nielsen fixed point theory.In this talk, l will give an overview of existing results on property Ro together with some openquestions.

Image Analysis using Persistent Homology | BIMSA Topology Seminar
AbstractDeep convolutional networks have proved to be extremely powerful in image analysis. However.they tend to be biased toward local features such as texture and often fail to capture the globalstructure of image and volume data. Persistent homology (PH), a tool from the emerging field oftopological data analysis, has been successfully used to detect global characteristics of data thatare ov...
