Variational method in generalized statistical mechanics. (English) Zbl 0808.60092

Summary: Concavity properties of a recently generalized (not necessarily extensive) entropy enable, among others, the generalization of the Bogolyubov inequality, hence of the variational method in equilibrium statistical mechanics.
