Moment functions of higher rank on some types of hypergroups

Ż Fechner, E Gselmann, L Székelyhidi - Semigroup Forum, 2023 - Springer
We consider moment functions of higher order. In our earlier paper, we have already
investigated the moment functions of higher order on groups. The main purpose of this work …

Spectral synthesis via moment functions on hypergroups

Ż Fechner, E Gselmann, L Székelyhidi - Forum Mathematicum, 2022 - degruyter.com
In this paper, we continue the discussion about relations between exponential polynomials
and generalized moment functions on a commutative hypergroup. We are interested in the …
