Abstract
Let be a connected graph. The revised edge Szeged index of is defined as , where (resp., ) is the number of edges whose distance to vertex (resp., ) is smaller than the distance to vertex (resp., ), and is the number of edges equidistant from both ends of , respectively. In this paper, the graphs with minimum revised edge Szeged index among all the unicyclic graphs with given diameter are characterized.
