The Stability

New set of one-loop finite GUT models is constructed. In particular there are some SU (N), N=5, 7, 9…models with two Higgs multiplets. The stability of finite solutions in UV and IR limits is investigated. The asymptotical behavior of the effective Yukawa and scalar couplings verify the asymptotical finiteness of the models. The renormalization group equations in curved space-time are also considered.

The One

GUT’s in curved space-time is considered. The set of asymptotically free and asymptotically conformally invariant models based on the SU (N) gauge group is constructed. The general solutions of renormalization group equations are considered as the special ones. Several SU (2N) models, which are finite in flat space-time (on the one-loop level) and asymptotically conformally invariant in external gravitational field are also presented.
