We discuss the influence of gravitational effects on the stabilization of the chromomagnetic vacuum. The one-loop effective potential for a covariantly constant SU(2) gauge field in S2 × R2 and T2 × R2 is calculated. A possibility of curvature-induced phase transitions between zero and nonzero chromomagnetic vacua is found —what is also confirmed through the calculation of the renormalization group (RG) improved effective potential on constant-curvature spaces with small curvature.
