Characterization of field homomorphisms through Pexiderized functional equations
Eszter Gselmann, Gergely Kiss, Csaba Vincze
The aim of this paper is to prove characterization theorems for field homomorphisms. More precisely, the main result investigates the following problem. Let be ar…
On the discrete Fuglede and Pompeiu problems
Gergely Kiss, Romanos Diogenes Malikiosis, Gábor Somlai +1
We investigate the discrete Fuglede's conjecture and Pompeiu problem on finite abelian groups and develop a strong connection between the two problems. We give a geometric conditio…
Characterizations of biselective operations
Jimmy Devillet, Gergely Kiss
Let be a nonempty set and let . We say that a binary operation is -selective if for all $x…
Derivations and differential operators on rings and fields
Gergely Kiss, Miklós Laczkovich
Let be an integral domain of characteristic zero. We prove that a function is a derivation of order if and only if belongs to the closure of the set of…
