Abstract
We investigate Aharonov-Bohm oscillations of the electrical current th rough a strongly correlated quantum dot embedded in an arbitrary scatt ering geometry in tile linear and nonlinear regime. We also study the temperature and flux dependence of tile thermopower S and find that it changes sign with temperature. At the temperature where S(T-0) = 0, t he thermal properties are strongly flux dependent as compared to the e lectrical conductance.
