Even-degeneracy of a random graph

Abstract

A graph is even-degenerate if one can iteratively remove a vertex of even degree at each step until at most one edge remains. Recently, Janzer and Yip showed that the Erd\H{o}s--Renyi random graph G(n,1/2)G(n,1/2) is even-degenerate with high probability, and asked whether an analogous result holds for any general G(n,p)G(n,p). In this paper, we answer this question for any constant p(0,1)p\in (0,1) in affirmation by proving that G(n,p)G(n,p) is even-degenerate with high probability.
