On the paper ,,Stability of Persistence Diagrams" by D. Cohen-Steiner, H. Edelsbrunner and J. Harer
The goal of the talk is to describe the contents of paper mentioned in the title. This interesting paperaddresses a number of topics. First, it introduces an analogue of a Morse function in the setting …

N-categories and physics
We will try do explain how n-categories naturally arise as the most convenient framework for modern physics, from quantum mechanics through field theories to quantum gravity.

Directed path spaces via discrete vector fields
Higher Dimensional Automaton is a cubical complex with two distinguished vertices: the initial and the final state and some labeling of vertices. Higher Dimensional Automata are used to model concurrent programs; possible states (respectively possible …

Topological Hochschild homology of KU
We give different descriptions of the topological Hochschild homology (THH) of the periodic complex topological K-theory ring spectrum KU as a commutative KU-algebra. We also describe the iterated THH of KU.

Gradients: the geometry and the ellipticity
The Stein-Weiss gradients - or shortly gradients are irreducible summands of a covariant derivative on a manifold equipped with a geometric structure. For the gradients and their compositions the main problems: the dependence on the …

Continuous k-regular maps
A continuous map from R^m to R^N or from C^m to C^N is called k-regular if the images of any k points are linearly independent. Given integers m and k a problem going back …

New periodicity criterion from Khovanov homology
We will discuss a new criterion, given in terms of Khovanov homology, for deciding whether a given knot is periodic or not. We will also discuss many examples showing the strength of the new criterion. …
