摘要：

We have considered the quantum behavior of a conformally induced gravity in the minimal Riemann-Cartan space. The regularized one-loop effective potential including the quantum fluctuations of the dilaton and the torsion fields in the Coleman-Weinberg sector gives a sensible phase transition for an inflationary phase in de Sitter space. For this effective potential, we have analyzed the semiclassical equation of motion of the dilaton field in the slow-rolling regime. © 1995 The American Physical Society.
