摘要：

The level statistics of disordered metallic grains with broken time reversal invariance is obtained from the Keldysh nonlinear a-model. The basic strategy of the approach-a nonperturbative integration over all saddle points of the a-model manifold-might prove useful in the analysis of problems involving disorder and interactions.
