Monomial functions, normal polynomials and polynomial equations
Eszter Gselmann, Mehak Iqbal
In this paper we consider generalized monomial functions (of possibly different degree) that also fulfill \[ f(P(x))= Q(g(x)) \qquad \left(x\i…
Polynomial equations for additive functions I. The inner case
Eszter Gselmann, Gergely Kiss
The aim of this sequence of work is to investigate polynomial equations satisfied by additive functions. As a result of this, new characterization theorems for homomorphisms and de…
Generalized derivations and generalized exponential monomials on hypergroups
Zywilla Fechner, Eszter Gselmann, László Székelyhidi
In one of our former papers {\it Endomorphisms of the measure algebra of commutative hypergroups arXiv:2204.07499 we considered exponential monomials on hypergroups and higher orde…
Moment functions of higher rank on polynomial hypergroups
Żywilla Fechner, Eszter Gselmann, László Székelyhidi
In this paper we consider generalized moment functions of higher order. These functions are closely related to the well-known functions of binomial type which have been investigate…
Endomorphisms and derivations of the measure algebra of commutative hypergroups
Zywilla Fechner, Eszter Gselmann, László Székelyhidi
Endomorphisms of the measure algebra of commutative hypergroups are investigated. We focus on derivations and higher order derivations which are closely related to moment function…
