Maximally symmetric Lorentzian manifold with constant negative scalar curvature. Anti-de Sitter space and de Sitter space are named after Willem de Sitter (1872–1934), professor of astronomy at Leiden University and director of the Leiden Observatory.

A standard topic in an introductory General Relativity (GR) course is the study of maximally symmetric solutions. These are flat (Minkowski) spacetime, de Sitter spacetime (obtained when the cosmological constant is positive) and Anti-de Sitter spacetime (when the cosmological constant is negative). While this last space has been of great interest in physics during the last fifteen years due to its central role in the correspondence between gauge theories and gravity, it is de Sitter space

De Sitter space and AdS/CFT correspondence · See more » Albert Einstein. Albert Einstein (14 March 1879 – 18 April 1955) was a German-born theoretical physicist who developed the theory of relativity, one of the two pillars of modern physics (alongside quantum mechanics). New!!: De Sitter space and Albert Einstein · See more » So, and in this case, de Sitter space in dimension greater than 2, anti-de Sitter space has only one boundary, not two boundaries. In fact, while rho equal to minus and plus infinity corresponds to these two boundaries of the two-dimensional de Sitter space, rho equals to 0 corresponds to the center of the, topologically, this guy's disk. 2018-06-06 Download Citation | Islands in de Sitter space | A bstract We consider black holes in 2d de Sitter JT gravity coupled to a CFT, and entangled with matter in a disjoint non-gravitating universe 2019-02-21 fqxi.org The past century in physics seems to lead in a surprising direction: away from physics as a description of objects and their interactions, and towar Dynamical compactiﬁcation from de Sitter space Sean M.

It has been notoriously difficult to construct a meta-stable de Sitter (dS) vacuum in string theory in a controlled approximation. This suggests the possibility that meta-stable dS belongs to the swampland. In this paper, we propose a swampland criterion in the form of. c c. In particular, this bound forbids dS vacua.

de Sitter space was also discovered, independently, and about the same time, by Tullio Levi de Sitter space is the subset deS = fhx;xi= a2 jx 2M5g: There is an isometric copy H4 q of hyperbolic space with x 0 <0. The induced metric on hyperbolic space is Riemannian and on de Sitter space is Lorentzian.

(noun) This relation allows us to explain the observable effect of the negative mass-square differences for neutrinos by applying de Sitter group for space-time symmetry in the interaction vertex and calculating particles masses as the eigenvalues of the Casimir operator in de Sitter space [52].

As it turns out, the occurrence of null lines is a very particular feature of de Sitter space. In Anti-de Sitter space definition is - the simplest hypothetical space-time that has negative curvature.
