The $k$-XORSAT threshold revisited

Combinatorics 2023-01-24 v1 Discrete Mathematics

Abstract

We provide a simplified proof of the random kk-XORSAT satisfiability threshold theorem. As an extension we also determine the full rank threshold for sparse random matrices over finite fields with precisely kk non-zero entries per row. This complements a result from [Ayre, Coja-Oghlan, Gao, M\"uller: Combinatorica 2020]. The proof combines physics-inspired message passing arguments with a surgical moment computation.
