Classification of Certain Rational Isoparametric Functions on Damek-Ricci Spaces
Balázs Csikós, Márton Horváth
We classify isoparametric functions on Damek-Ricci spaces which can be written in terms of the standard coordinates on the half-space model as a polynomial function divid…

Sphere-like isoparametric hypersurfaces in Damek-Ricci spaces
Balázs Csikós, Márton Horváth
Locally harmonic manifolds are Riemannian manifolds in which small geodesic spheres are isoparametric hypersurfaces, i.e., hypersurfaces whose nearby parallel hypersurfaces are of…
