Resilience for tight Hamiltonicity

Combinatorics 2021-05-11 v1

Abstract

We prove that random hypergraphs are asymptotically almost surely resiliently Hamiltonian. Specifically, for any γ>0\gamma>0 and k3k\ge3, we show that asymptotically almost surely, every subgraph of the binomial random kk-uniform hypergraph G(k)(n,nγ1)G^{(k)}\big(n,n^{\gamma-1}\big) in which all (k1)(k-1)-sets are contained in at least (12+2γ)pn\big(\tfrac12+2\gamma\big)pn edges has a tight Hamilton cycle. This is a cyclic ordering of the nn vertices such that each consecutive kk vertices forms an edge.
