About Resolvent Energy Calculator

A resolvent energy calculator computing ER(G) = Σ 1/(n-λᵢ) where λᵢ are adjacency eigenvalues. Gutman-Furtula (2001). Alternative to graph energy. ER characterizes molecular branching. ER ≥ 1 always. More discriminating than EE for some graph families. Client-side.
