We discuss the fundamental properties of general entropic forms based on arbitrary concave functions and their application to current problems of quantum information theory. It is first shown that the extended formalism allows to construct, for a two-qubit system, least biased density operators...

Three results are presented: First, we solve the problem of persistence of dissipation for reduction of kinetic models. Kinetic equations with thermodynamic Lyapunov functions are studied. Uniqueness of the thermodynamic projector is proven: There exists only one projector which transforms any...
