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

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

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
