Abstract
- The Harary index of a connected (molecular) graph is defined as the sum of reciprocals of distances between all its pairs of vertices. In this paper, we characterize the extremal Eulerian graphs (with a fixed number of vertices) with greatest and smallest Harary indices and characterize the Harary indices of two special type of Eulerian graphs.
