A graph G is said to be degree preservable if for any spanning
tree T of G, there exists a vertex v whose degree in T is equal to its degree
in G. In this paper, we introduce the notion of vertex degree preservability
of a graph G as the least number of edges that should be removed from G in
order to get a graph G' which is degree preservable. We compute the vertex
degree preservability for some of the most common families of graphs such as:
bipartite and complete graphs.
