Abstract
The problem of nonlinear resonant tunneling through an Anderson impurity is investigated in this letter using a combined -approach of Keldysh formalism and 1/N expansion at zero temperature. We find that to order 1/N, the Kondo resonance is not destroyed by any finite potential difference between external probes. The resulting one-electron Green's functions and differential conductance are presented. The effect of finite temperature is discussed
