Abstract

We prove that if GG is a graph and r1,...,rkZ0r_1, ..., r_k \in \mathbb{Z}_{\geq 0} such that i=1kriΔ(G)+2k\sum_{i=1}^k r_i \geq \Delta(G) + 2 - k then V(G)V(G) can be partitioned into sets V1,...,VkV_1, ..., V_k such that Δ(G[Vi])ri\Delta(G[V_i]) \leq r_i and G[Vi]G[V_i] contains no non-complete rir_i-regular components for each 1ik1 \leq i \leq k. In particular, the vertex set of any graph GG can be partitioned into Δ(G)+23\left \lceil \frac{\Delta(G) + 2}{3} \right \rceil sets, each of which induces a disjoint union of triangles and paths.
