Rational curvature invariants for 2-complexes

Group Theory 2024-05-16 v3 Geometric Topology

Abstract

New invariants for 2-dimensional cell complexes are defined, which can be interpreted as curvature bounds. These invariants are proved to be rational and computable in a companion article. This document is a survey that collects theorems about these invariants, computes examples, and lays out a programme of conjectures.
