Geometrical and Topological Dimensions of the Diamond,geometrical features of the adamantane molecule are examined in detail. It is shown that the adamantane molecule has the dimension 4. The connection ways of the adamantane molecules are investigated on the basis of their geometric properties. Topological properties of the diamond, a 3-periodic net o

Topological Indices of 3-Generalized Fullerenes,onnected cubic planar graph . = (.;.) is called .generalized fullerene if it has two .gons and all other faces are pentagons and hexagons. The aim of this chapter is to compute some distance topology of eight infinite sequences of 3-generalized fullerene.

The Informal Core of Formal Logicrmation pathways. In our days the most well-known carbon nanostructures are the fullerenes, the nanotubes, and the graphene. The fullerenes and nanotubes can be thought of as being formed from graphene sheets, i.e., single layers of carbon atoms arranged in a honeycomb lattice. Usually the nature do

The Informal Core of Formal Logicices whose removal disconnects the graph. A fullerene graph is a cubic, planar, and 3-connected whose faces are all pentagons or hexagons. A fullerene is a molecule, that is, its molecular graph is a fullerene graph. In 1991, Graovac and Pisanski (1991) proposed an algebraic modification of the Wien
