A family of nonextensive entropies. (English) Zbl 0940.82008

Summary: A generalized nonextensive two-parameter entropy is developed, along lines which unify current nonextensive frameworks. It recovers, as particular cases, the Tsallis and symmetric entropies, as well as the Boltzmann-Gibbs entropy. The properties of the new \((q,q'\))-entropy are analysed.
