On a conjecture of Nikiforov concerning the minimal $p$-energy of connected graphs

Quanyu Tang, Yinchen Liu, Wei Wang

For a given simple graph \( G \), the \( p \)-energy of \( G \), denoted by \( \mathcal{E}_p(G) \), is defined as the sum of the \( p \)-th power of the absolute values of the eige…
