Harary index, binding number and toughness of graphs

Given a connected (molecular) graph , its Harary index ( ) is defined by the reciprocal sum of the distances between all unordered pairs of vertices of . Lower bounds on the graph vulnerability parameters binding number and toughness have been often used to determine that the graph has a certain...
