Abstract
Exchange interaction within a quantum dot strongly affects the transport through it in the Kondo regime. In a striking difference with the results of the conventional model, where this interaction is neglected, here the temperature and magnetic field dependence of the conductance may become nonmonotonic: its initial increase follows by a drop when temperature and magnetic field are lowered.
