Three coordinate systems are used: global coordinates, May 31, 2019 - In mathematics and physics, n-dimensional anti-de Sitter space ( AdSn) is a maximally symmetric Lorentzian manifold with constant negative Feb 13, 2013 Dias et al have explored recently in order to check if a spacetime of special interest in modern physics, called Anti de Sitter (AdS), is stable or not.

A de Sitter universe is a cosmological solution to the Einstein field equations of general relativity, named after Willem de Sitter. It models the universe as spatially flat and neglects ordinary matter, so the dynamics of the universe are dominated by the cosmological constant , thought to correspond to dark energy in our universe or the inflaton field in the early universe .

Interestingly, the proper char-acterization of dynamics in such asymptotically future dS spacetimes - the analog of the S-matrix for asymptotically Minkowski spacetimes or boundary correlators for asymp-totically anti-de Sitter (AdS) spacetimes - remains an open problem.

This section also contains a derivation, missing in previous treatments, of the. De-sitter space is a mathematical construct, it gives a starting point to give coordinates in space/time.

There are two main con The Herschel Space Observatory is a European Space Agency space observatory sensitive to the far infrared and submillimetre wavebands. The Herschel Observatory is capable of seeing the coldest and dustiest objects in space; for example, cool cocoons where stars form and dusty galaxies just starting to bulk up with new stars. [via NASA/JPL] 2001-09-30 In this module we derive constant curvature de Sitter and anti de Sitter solutions of the Einstein equations with non-zero cosmological constant. We describe the geometric and causal properties of such space-times and provide their Penrose-Carter diagrams. We provide coordinate systems which cover various patches of these space-times.

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].

Given these conditions, one can define de Sitter space to be the maximally symmetric solution to the vacuum Einstein equations with positive cosmological constant. Just for completeness, note that Anti de Sitter space is the maximally symmetric solution to Einstein's equations with negative cosmological constant.

In particular, this bound forbids dS vacua. 2018-05-02 · space that may be relevant for the famed AdS/CFT (Anti-de Sitter space/conformal field theory) correspondence, also known as holographic duality or gauge/gravity duality. 2 The Simplest Answer The simplest answer to whether our universe is curved or flat is this. In 4D (3 space and 1 time, often called 3+1 space), our universe is curved. Definition of de Sitter space : the simplest hypothetical space-time that has positive curvature Those clues, in particular, may be applied to the most symmetric solution of Einstein's equations with positive cosmological constant and no matter— de Sitter space .
