摘要：
The general Dynamical Mean-Field Theory approach based on the expansion over electron hopping and local nature of the irreducible parts (cumulants) of the Green's functions in infinite dimensions is developed for the description of correlated hopping. In order to calculate the thermodynamical functions the new grand canonical potential functional is proposed that allows to build the Phi-derivatible theory without introducing self-energy.
