AbstractIn the course of three seminars we will discuss the classic constructions of Goodwillie calculus of functors. We are interested in the applications of this theory in unstable homotopy theory and our end goal is to understand, whenever Goodwillie tower of the loop-suspension functor admits a homotopy decomposition in sense of Selick-Wu. Along the way we will try to reformulate Goodwillie...
AbstractWe discuss the notions of path homology and homotopy of digraphs. The following topic will bepresented.. Homology groups of digraphs.. Homotopy of digraph maps and digraphs. lnvariance of homology groups under homotopy.Fundamental group of a digraph. Invariance of the fundamental group under homotopy.Relation between the fundamental group and first homology group.Speaker IntroProfessor ...
