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 valencies of all the atoms are calculated and their significance is discussed. It is ...
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...
