| Abstract: | It is shown that SU(3)one-link integrals which arise in 2nd order variational-cumulant expansion in SU(3)lattice gauge theory can be calculated by using four fundamental SU(3)group integrals.The definite integral expres-
sions of these four SU(3)group integrals in the weak coupling regions are obtained by steepest descent method.All these integrals can be numerically evaluated easily. |
