Geometric, Algebraic, and Topological Combinatorics

Abstract

The 2019 Oberwolfach meeting “Geometric, Algebraic and Topological Combinatorics” was organized by Gil Kalai (Jerusalem), Isabella Novik (Seattle), Francisco Santos (Santander), and Volkmar Welker (Marburg). It covered a wide variety of aspects of Discrete Geometry, Algebraic Combinatorics with geometric flavor, and Topological Combinatorics. Some of the highlights of the conference included (1) Karim Adiprasito presented his very recent proof of the g-conjecture for spheres (as a talk and as a “Q&A” evening session) (2) Federico Ardila gave an overview on “The geometry of matroids”, including his recent extension with Denham and Huh of previous work of Adiprasito, Huh and Katz.
