  Article:   MAXIMAL HARARY INDEX OF UNICYCLIC GRAPHS WITH A GIVEN MATCHING NUMBER.

Authors:  MIRCEA V. DIUDEA.
 
       
         
  Abstract:   The Harary index is defined as the sum of reciprocals of distances between all the vertex pairs of a connected graph. In this paper we present upper bounds on Harary index of unicyclic graphs with a given matching number and characterize the extremal graphs for which the upper bounds on Harary index are attained.

Key Words: Graph, Reciprocal distance, Harary Index, upper bound
