High degree graphs contain large-star factors

Combinatorics 2008-10-14 v1

Abstract

We show that any finite simple graph with minimum degree dd contains a spanning star forest in which every connected component is of size at least Ω((d/logd)1/3)\Omega((d/\log d)^{1/3}). This settles a problem of J. Kratochvil.
