Calculations, within the CNDO framework, have been performed on a wide range of molecules containing elements of the first and second rows of the Periodic Table. By use of the density matrix elements, the valenc
Let G be a group and S be a subset of G such that e / S and S-1 S. Then Cay(G, S) is a simple undirected Cayley graph whose vertices are all elements of G and two vertices x and y are adjacent if and only if xy-1 S. The size of...
