- Title
单圈图的 Steiner Wiener 指数的极值问题.
- Authors
张杰; 姬燕
- Abstract
Wiener index is an important chemical index in chemical graph theory, defined as the sum of distances between all pairs of vertices. A generalization of the Wiener index, called the Steiner Wiener index, takes the sum of the Steiner distances over all sets S of cardinality k. The Steiner distance of vertices in a set S is the minimum size of a connected subgraph that contain these vertices. We consider the extremal problems with respect to the Steiner Wiener index among all unicyclic graphs.
