Classification of rotational surfaces in Euclidean space satisfying a linear relation between their principal curvatures [PDF]

Mathematische Nachrichten, 2020
AbstractWe classify all rotational surfaces in Euclidean space whose principal curvatures κ1 and κ2 satisfy the linear relation , where a and b are two constants. As a consequence of this classification, we find closed (embedded and not embedded) surfaces and periodic (embedded and not embedded) surfaces with a geometric behaviour similar to Delaunay ...

Low-dimensional de Sitter quantum gravity

Journal of High Energy Physics, 2020
We study aspects of Jackiw-Teitelboim (JT) quantum gravity in two-dimensional nearly de Sitter (dS) spacetime, as well as pure de Sitter quantum gravity in three dimensions.
