The change of vertex energy when joining trees

Spectral Theory 2024-02-06 v1 Combinatorics

Abstract

In this manuscript we study how the vertex energy of a tree is affected when joined with a bipartite graph. We find an alternating pattern with respect to the coalescence vertex: the energy decreases for vertices located at odd distances and increases for those located at even distances.
