We reene the techniques of Beigel, Gill, Hertrampf 4] who investigated polynomial time counting classes, in order to make them applicable to the case of logarithmic space. We deene the complexity classes MOD k L and demonstrate their signiicance by proving that all standard problems of linear algebra over the nite rings Z/kZ are complete for these classes. We then deene new complexity classes LogFew and LogFewNL and identify them as adequate logspace versions of Few and FewP. We show thatâ€¦Â CONTINUE READING
