چکیده
|
The corona product g h of two graphs g and h is obtained by taking one copy of gand jv (g)j copies of h; and by joining each vertex of the i-th copy of h to the i-th vertex of g, where1 i jv (g)j. in this paper, exact formulas for the eccentric distance sum and the edge revisedszeged indices of the corona product of graphs are presented. we also study the conditions underwhich the corona product of graphs produces a median graph.
