Abstract: The vertex PI index is a distance-based molecular structure descriptor, that recently found numerous chemical applications. In this letter we obtain a lower bound on the vertex PI index of a connected graph in terms of number of vertices, edges, pendent vertices, and clique number, and characterize the extremal graphs.
