Description
The contribution of the U(1) and simple group factors Sk of the background gauge group S=ΠkSk to the number of massless fermion generations in superstring theories is examined. Unlike the semisimple case when only SU(n) factors contribute to the generation number, if the abelian factors are present, all groups contained in S contribute to it. (orig.)
