Abstract:
The Wiener index of the graph G is defined as the sum over all unordered pairs of distinct vertices in G. The Wiener index of geometrically planar triangular chains is characterized. It is showed that the linear triangular chain and helicene triangular chain attain the maximum Wiener index and minimum Wiener index, respectively.
Key words: triangular chains; Wiener index; extreme
