Combinatorics of Pseudocircle Arrangements

Stefan Felsner (TU Berlin)

22-Apr-2021, 14:00-16:00 (3 years ago)

Abstract: In this talk we survey results for pseudocircle arrangements. Along the way we present several open problems. Among others we plan to touch the following topics: * The taxonomy of classes of pseudocircle arrangements. * The facial structure with emphasis on triangles and digons. * Circularizability. * Coloring problems for pseudocircle arrangements. The talk includes work of Grünbaum, Snoeyink, Pinchasi, Scheucher, and others.
