Limit theorems for Randic index for Erdős-Renyi graphs
Laura Eslava, Sayle Sigarreta, Arno Siri-Jegousse
We prove that the generalized Randic index over graphs following the Erdős-Renyi model, for both the sparse and dense regimes, is concentrated around its mean when the number of ve…

The change of vertex energy when joining trees
Octavio Arizmendi, Saylé Sigarreta
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: t…
