It seems reasonable to consider concavity (with regard to all probability distributions) and stability (under …, through appropriate optimization, yield the Beck–Cohen superstatistics. We briefly review here the proof of stability of S … concavity and stability appears to be very helpful to identify physically admissible entropic forms. …
