Extensivity and nonextensivity of two-parameter entropies

In this paper, we investigate two-parameter entropies and obtain some conditions for their extensivity. By using a generalized (k,r)-product, correlations for subsystems are related to the joint probabilities, so that the entropy remains extensive.
