Abstract

Heun functions are important for many applications in
Mathematics, Physics and in thus in interdisciplinary phenomena modelling. They satisfy second order differential
equations and are usually represented by power series. Closed forms and
simpler polynomial representations are useful. Therefore, we study and derive closed forms for
several families of Heun functions related to classical entropies. By
comparing two expressions of the same Heun function, we get several
combinatorial identities generalizing some classical ones.

Keywords
