On functional equations characterizing derivations: methods and examples
Eszter Gselmann, Gergely Kiss, Csaba Vincze
Functional equations satisfied by additive functions have a special interest not only in the theory of functional equations, but also in the theory of (commutative) algebra because…
Lazy orbits: an optimization problem on the sphere
Csaba Vincze
Non-transitive subgroups of the orthogonal group play an important role in the non-Euclidean geometry. If is a closed subgroup in the orthogonal group such that the orbit of a…
On convex closed planar curves as equidistant sets
Csaba Vincze
The equidistant set of two nonempty subsets and in the Euclidean plane is a set all of whose points have the same distance from and . Since the classical conics can…
On the generalization of Erdős-Vincze's theorem about the approximation of closed convex plane curves by polyellipses
Csaba Vincze, Zoltán Kovács, Zsófia Fruzsina Csorvássy
A polyellipse is a curve in the Euclidean plane all of whose points have the same sum of distances from finitely many given points (focuses). The classical version of Erdős-Vincze'…
On spectral synthesis in varieties containing the solutions of inhomogeneous linear functional equations
Gergely Kiss, Csaba Vincze
As a continuation of our previous work \cite{KV2} the aim of the recent paper is to investigate the solutions of special inhomogeneous linear functional equations by using spectral…
On spectral analysis in varieties containing the solutions of inhomogeneous linear functional equations
Gergely Kiss, Csaba Vincze
The aim of the paper is to investigate the solutions of special inhomogeneous linear functional equations by using spectral analysis in a translation invariant closed linear subspa…
