### Rainbow $H$-factors

#### Abstract

An *$H$-factor* of a graph $G$ is a spanning subgraph of $G$ whose connected components are isomorphic to $H$. Given a properly edge-colored graph $G$, a *rainbow* $H$-subgraph of $G$ is an $H$-subgraph of $G$ whose edges have distinct colors. A *rainbow $H$-factor* is an $H$-factor whose components are rainbow $H$-subgraphs. The following result is proved. If $H$ is any fixed graph with $h$ vertices then every properly edge-colored graph with $hn$ vertices and minimum degree $(1-1/\chi(H))hn+o(n)$ has a rainbow $H$-factor.
