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…
Spectral synthesis via moment functions on hypergroups
Żwilla Fechner, Eszter Gselmann, László Székelyhidi
In this paper we continue the discussion about relations between exponential polynomials and generalized moment generating functions on a commutative hypergroup. We are interested…
Moment functions and exponential monomials on commutative hypergroups
Żywilla Fechner, Eszter Gselmann, László Székelyhidi
The purpose of this paper is to prove that if on a commutative hypergroup an exponential monomial has the property that the linear subspace of all sine functions in its variety is…
Moment functions on groups
Żywilla Fechner, Eszter Gselmann, László Székelyhidi
The main purpose of this work is to prove characterization theorems for generalized moment functions on groups. According one of the main results these are exponential polynomials…
