Title: Chromatic and Periodic Persistent Homology

Professor Herbert Edelsbrunner, Institute of Science and Technology Austria

Abstract: Advances in spatial biology motivate the extension of persistent homology to colored data. The computed information is expressed in a table of six multisets in the plane, referred to as the 6-pack of chromatic persistence diagrams. Independently, crystalline materials motivate the generalization of persistent homology to periodic data, and we make first steps in this direction by annotating the merge tree of the quotient with monomials, whose degree and coefficients encode the growth rate and the density of the connected components.
