Query: Effective action approach to dynamical generation of fermion mixing   In this paper we discuss a mechanism for the dynamical generation of flavor
mixing, in the framework of the Nambu--Jona Lasinio model. Our approach is
illustrated both with the conventional operatorial formalism and with
functional integral and ensuing one-loop effective action. The results obtained
are briefly discussed.
