Abstract
The vertex PI index and Szeged index are distance-based topological index which reflect certain structural
features of organic molecules. Each structural feature of such organic molecule can be expressed as a graph. In this paper,
we determine the vertex PI index and Szeged index of fan molecular graph, wheel molecular graph, gear fan molecular
graph, gear wheel molecular graph, and their r-corona molecular graphs.
