We investigate four-fermion interactions with N-component fermion in Einstein universe for arbitrary space-time dimensions (2 ≤ D<4). It is found that the effective potential for composite operator ψψ is calculable in the leading order of the 1/N expansion. The resulting effective potential is analyzed by varying the curvature of the space-time and is found to exhibit the symmetry restoration through the second-order phase transition. The critical curvature at which the dynamical fermion mass disappears is analytically calculated.
