2-FORM GRAVITY AND THE GENERATION OF SPACE-TIME

In the framework oi the two-form gravity, which is classically equival ent to the Einstein gravity, the one-loop effective potential for the conformal factor of metric is calculated in the finite volume and in t he finite temperature by choosing a temporal gauge condition. There ap pears a quartically divergent term which cannot be removed by the reno rmalization of the cosmological term and we find there is only one non trivial minimum in the effective potential. If the cutoff scale has a physical meaning, e.g. the Planck scale Coming from string theory this minimum might explain why the space-time is generated, i.e. why the c lassical metric has a nontrivial value.
