Gergely Kiss, Jens Schwaiger
Investigating the future value of a capital invested at date at date the "natural" condition has lost its naturality because of the strange…
Optimal embedded and enclosing isosceles triangles
Aron Ambrus, Monika Csikos, Gergely Kiss +2
Given a triangle , we study the problem of determining the smallest enclosing and largest embedded isosceles triangles of with respect to area and perimeter. This problem wa…
Isometric rigidity of Wasserstein spaces: the graph metric case
Gergely Kiss, Tamás Titkos
The aim of this paper is to prove that the -Wasserstein space is isometrically rigid for all whenever is a countable graph metric space. As a co…
Translation invariant linear spaces of polynomials
Gergely Kiss, Miklós Laczkovich
A set of polynomials is called a {\it submodule} of if is a translation invariant linear subspace of . We pre…
Characterization of quasi-arithmetic means without regularity condition
Pál Burai, Gergely Kiss, Patricia Szokol
In this paper we show that bisymmetry, which is an algebraic property, has a regularity improving feature. More precisely, we prove that every bisymmetric, partially strictly monot…
Spectral sets and tiles in
Thomas Fallon, Gergely Kiss, Gábor Somlai
In this paper we study Fuglede's conjecture on the direct product of two cyclic groups. After collecting the known results we prove that Fuglede's conjecture holds on $\mathbb{Z}_{…
