Title: Monotone circuit complexity of matching

Abstract

We show that the perfect matching function on $n$-vertex graphs

requires monotone circuits of size $2^{n^{\Omega(1)}}$. This

improves on the $n^{\Omega(\log n)}$ lower bound of Razborov (1985).

Our proof uses the standard approximation method together with a new

sunflower lemma for matchings.
