چکیده
|
we study the gutman index gut(g) and the edge-wiener index we(g) of connected graphs g of given order n and edge-connectivity λ . we show that the bound gut(g)≤24⋅355(λ+1)n5+o(n4) is asymptotically tight for λ≥8 . we improve this result considerably for λ≤7 by presenting asymptotically tight upper bounds on gut(g) and we(g) for 2≤λ≤7 .
