摘要：

We calculated the chiral condensate and the dressed Polyakov loop in the space-time R x S-3 and R x H-3. The chiral condensate is the order parameter for the chiral phase transition, whereas the dressed Polyakov loop is the order parameter for the deconfinement phase transition. When there is a current mass, critical points for the chiral and deconfinement phase transitions are different in the crossover region. We show that the difference is changed by the gravitational effect.
