Title: Structural properties in hypercubes.
Abstract:
In this talk we review some structural questions on subgraphs of the hypercube of dimension n. We present a simpler proof of Huang’s 2019 result that any subgraph of $H_n$ on more than half the number of vertices has a vertex of degree at least $\sqrt{n}$. We present some strengthening of the result, and we observe a connection to an older question of Erdos who asked: how many edges of $H_n$ one should take to guarantee existence of a 4-cycle.
This is a joint work with Sophie Laplante, Anupa Sunni, and Zhouningxin Wang
