THE UNITARY GROUP APPROACH TO BONDED FUNCTIONS T.H. Seligman Instituto de Fisica Universidad Nacional Autbnoma de Mexico Mexico 20, D.F. ABSTRACT The use of Lie algebraic techniques connected with the groups SU(N) and GL(N) for the construction of bonded n-electron functions and the evaluation of their matrix elements, is summarized. Some simlifications arising from the use of restricted basis sets are discussed. J.
