To a question on the existence of regular mosaics on a hyperbolic plane of positive curvature
L. Romakina;Abstract
A hyperbolic plane $\widehat{H}$ of positive curvature can be realized on ideal domain of a Lobachevskii plane. The plane $\widehat{H}$ is the projective Cayley\,--\,Klein model of two-dimensional de Sitter space. In this work it is proved that there is no regular mosaic on the plane $\widehat{H}$.
