New Formulae for the Decycling Number of Graphs
A set S of vertices of a graph G is called a decycling set if G−S is acyclic. The minimum order of a decycling set is called the decycling number of G, and denoted by ∇(G). Our results include: (a) For any graph G,, where T is taken over all the spanning trees of G and α(G − E(T)) is the independenc...
