Lower bound of the energy of a complex unit gain graph in terms of the matching number of its underlying graph

Yuxuan Li

We establish a lower bound for the energy of a complex unit gain graph in terms of the matching number of its underlying graph, and characterize all the complex unit gain graphs wh…
