Juan Pablo Vigneaux (Université Paris Denis Diderot, France)
In this talk, I introduce a space (topos) related to random experiments and an adapted cohomology theory. I describe the cohomological characterization of Shannon entropy, Tsallis entropy and the Fontené-Ward multinomial coefficients (a generalized version of the usual ones), as well as a functorial relation between them. Finally, I comment about a generalization of Shannon theory in which messages are finite vector spaces.
