Composability and Generalized Entropy
arXiv:cond-mat/9906377 · doi:10.1016/S0375-9601(99)00678-7
Abstract
We address in this paper how tightly the composability nature of systems: $S_{A+B} =Ω(S_A, S_B)$ constrains definition of generalized entropies and investigate explicitly the composability in some ansatz of the entropy form.
