Abstract
The phase structure of the d=3 Nambu-Jona-Lasinio model in curved spacetime is considered to leading order in the 1/N--expansion and in the linear curvature approximation. The possibility of a curvature-induced first-order phase transition is investigated numerically. The dynamically generated fermionic mass is calculated for some values of the curvature.
