Triangle-tilings in graphs without large independent sets

preprint2016arXivOpen access

Abstract

We study the minimum degree necessary to guarantee the existence of perfect and almost-perfect triangle-tilings in an nn-vertex graph GG with sublinear independence number. In this setting, we show that if δ(G)≥n/3+o(n)δ(G) \ge n/3 + o(n) then GG has a triangle-tiling covering all but at most four vertices. Also, for every r≥5r \ge 5, we asymptotically determine the minimum degree threshold for a perfect triangle-tiling under the additional assumptions that GG is KrK_r-free and nn is divisible by 33.
