The edge Szeged index is a new molecular structure descriptor equal to the sum of products mu(e)mv(e) over all edges e = uv of the molecular graph G, where mu(e) is the number of edges which its distance to vertex u is smaller than the distance to vertex v, and nv(e) is defined analogously. In this paper, the edge Szeged index of one-pentagonal carbon nanocone CNC5[n] is computed for the first ...

Recently the vertex Padmakar–Ivan (PI v) index of a graph G was introduced as the sum over all edges e = uv of G of the number of vertices which are not equidistant to the vertices u and v. In this paper the vertex PI index and Szeged index of bridge graphs are determined. Using these formulas, the vertex PI indices and Szeged indices of several graphs are computed.

A new unsymmetric matrix, SZu (unsymmetric Szeged matrix) is proposed by analogy to the matrix CJu (unsymmetric Cluj matrix) [1,2]. It is defined and exemplified both for acyclic and cycle-containing structures. Its relation with the CJu matrix is discussed. The derived Szeged numbers are compared to the Wiener matrixand Cluj matrixderived numbers and tested for separating and correlating abili...
