{0, 2}-Degree free spanning forests in graphs

Let G be a graph and S be a set of non-negative integers. By an S-degree free spanning forest of G we mean a spanning forest of G with no vertex degree in S. In this paper we study the existence of {0, 2}-degree free spanning forests in graphs. We show that if G is a graph with minimum degree at least 4, then there exists an {0, 2}-degree free spanning forest. Moreover, we show that every 2-connected graph with maximum degree at least 5 admits a {0, 2}-degree free spanning forest.
