Review: In this paper, sufficient conditions are given in terms of \delta(G) and \Delta(T), for a graph G with n vertices to contain a tree T with n vertices. One of these sufficient conditions is used to calculate some of the Ramsey numbers for the pair tree-star. Also necessary conditions are given, in terms of \delta(G), for a graph G with n vertices to contain all trees with n vertices.
