The Wiener index is defined as the summation of distances between all pairs of vertices in a graph or in a hypergraph. Both models—graph-theoretical and hypergraph-theoretical—are used in mathematical chemistry for quantitatively studying physical and chemical properties of classical and nonclassical organic compounds. In this paper, we consider relationships between hypertrees and trees and hypercycles and cycles with respect to their Wiener indices.

寻找超图维纳指数的新方法

维纳指数定义为图形或超图形中所有顶点对之间的距离之和。图形理论和超图理论这两种模型都用于数学化学中，以定量研究经典和非经典有机化合物的物理和化学性质。在本文中，我们考虑了超树和树与超周期和周期之间的关系，并讨论了它们的维纳指数。
