Such relations are even necessary to ensure all-loop finiteness in Finite Unified Theories, which have vanishing $β$-functions beyond the unification point. We elucidate this alternative way of unification, and then present its phenomenological consequences in $SU(5)$-based models.9 pages, MPI-Ph/94-55, HD-THEP-94-34, KANAZAWA-94-18High Energy Physics - Theorytext
