Elementary hypergeometric functions, Heun functions, and moments of MKZ operators
Ana Maria Acu, Ioan Rasa
We consider some hypergeometric functions and prove that they are elementary functions. Consequently, the second order moments of Meyer-Konig and Zeller type operators are elementa…
Inequalities for indices of coincidence and entropies
Alexandra Maduta, Diana Otrocol, Ioan Rasa
We consider a probability distribution depending on a real parameter . As functions of , the Rényi entropy and the Tsallis entropy can be expressed in terms of the associated…
A Nice Representation for a Link between Baskakov- and Szász-Mirakjan-Durrmeyer Operators and their Kantorovich Variants
Margareta Heilmann, Ioan Raşa
In this paper we consider a link between Baskakov-Durrmeyer type operators and corresponding Kantorovich type modifications of their classical variants. We prove a useful represent…
Discrete Operators associated with Linking Operators
Margareta Heilmann, Fadel Nasaireh, Ioan Raşa
We associate to an integral operator a discrete one which is conceptually simpler, and study the relations between them.
Heun functions and combinatorial identities
Adina Barar, Gabriela Raluca Mocanu, Ioan Rasa
We give 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 ide…
Heun functions related to entropies
Adina Barar, Gabriela Raluca Mocanu, Ioan Rasa
We consider the indices of coincidence for the binomial, Poisson, and negative binomial distributions. They are related in a simple manner to the Rényi entropy and Tsallis entropy.…
