Abstract :
The Gutman index and degree distance of a connected graph GG are defined as
Gut(G)=∑{u,v}⊆V(G)d(u)d(v)dG(u,v),
and
DD(G)=∑{u,v}⊆V(G)(d(u)+d(v))dG(u,v),
respectively, where d(u) is the degree of vertex uu and dG(u,v) is the distance between vertices u and v. In this paper, through a recurrence equation for the Wiener index, we study the first two
moments of the Gutman index and degree distance of increasing trees.
