Adiabatic pumping through a quantum dot is investigated under the strong Coulomb interaction using the slave boson mean-field theory. The pumped current is driven by time-dependent gate voltages applied to the dot. We illustrate the pumped current peculiar to the Kondo effect.

## Abstract We introduce a mathematical setup for charge transport in quantum pumps connected to a number of external leads. It is proved that under rather general assumption on the Hamiltonian describing the system, in the adiabatic limit, the current through the pump is given by a formula of Bütt
