Hypercube minor-universality
Itai Benjamini, Or Kalifa, Elad Tzalik
A graph is -minor-universal if every graph with at most edges (and no isolated vertices) is a minor of . We prove that the -dimensional hypercube, , is $Ω\le…

Thick embeddings into the Heisenberg group and coarse wirings into groups with polynomial growth
Or Kalifa
We bound the volume of thick embeddings of finite graphs into the Heisenberg group, as well as the volume of coarse wirings of finite graphs into groups with polynomial growth. Thi…
