摘要：
Let G = (V . E) be a simple graph with vertex set.. and edge set... The Sombor index of the graph G is a degree-based topological index, defined as SO(G) = Sigma(uvE) root d(u)(2)i + d(v)(2), in which d(x) is the degree of the vertex x is an element of V for x = u.v.In this paper, we characterize the extremal trees with given degree sequence that minimize and maximize the Sombor index.
