Translation-like Apollonius and triangular surfaces in non-constant curvature Thurston geometries
Géza Csima, Jenő Szirmai
In the present paper we deal with non-constant curvature Thurston geometries \cite{M97}, \cite{S}, \cite{Sz22-3},\cite{W06}. We define and determine the generalized trans\-lation-l…

New lower bound for the optimal congruent geodesic ball packing density of screw motion groups in space
Arnasli Yahya, Jenő Szirmai
In this paper, we present a new record for the densest geodesic congruent ball packing configurations in geometry, generated by screw motion grou…

Interior angle sums of geodesic triangles and translation-like isoptic surfaces in Sol geometry
Géza Csima, Jenő Szirmai
After having investigated the geodesic triangles and their angle sums in Nil and geometries we consider the analogous problem in Sol space that is one of the e…
