Sharp threshold for rigidity of random graphs

Combinatorics 2022-09-14 v2 Probability

Abstract

We consider the Erd\H{o}s-R\'enyi evolution of random graphs, where a new uniformly distributed edge is added to the graph in every step. For every fixed d1d\ge 1, we show that with high probability, the graph becomes rigid in Rd\mathbb R^d at the very moment its minimum degree becomes dd, and it becomes globally rigid in Rd\mathbb R^d at the very moment its minimum degree becomes d+1d+1.
