Title: Improved lower bound on the number of finite p-groups.  

Abstract: The number of finite p-groups of order p^k is known to be upper bounded by
p^(2k^3/27+O(5k/2)) (Newman and Seeley), and lower bounded by p^(2k^3/27-4k^2/9) (G.
Higman, 1960).  In this talk I will describe how to obtain an improved lower bound
p^(2k^3/27-O(k)).  Interestingly, the key idea is inspired by a result from random graph
theory (Babai-Erdos-Selkow, 1980).  

This is based on a joint work with Yinan Li at UTS.
