ISOR Colloquium

"Shape, Homology, Persistence, and Stability"

Speaker: Herbert Edelsbrunner (Institute of Science and Technology Austria)

HS 7 OMP1 (#1.303)
Oskar-Morgenstern-Platz 1, 1090 Wien


My personal journey to the fascinating world of geometric forms started 30 years ago with the invention of alpha shapes in the plane. It took about 10 years before we generalized the concept to higher dimensions, we produced working software with a graphics interface for the 3-dimensional case, and we added homology to the computations. This foreshadowed the inception of persistent homology, because it suggested the study of filtrations to capture the scale of a shape or data set. Importantly, this method has fast algorithms. The arguably most useful result on persistent homology is the stability of its diagrams under perturbations.
