Willem de Sitter, född den 6 maj 1872, död den 20 november 1934, var en namnkunnig matematiker, astronom och kosmolog i Nederländerna.Han blev mest uppmärksammad för sina bidrag till utvecklingen av den fysikaliska kosmologin.

2001-09-30 · These lectures present an elementary discussion of some background material relevant to the problem of de Sitter quantum gravity. The first two lectures discuss the classical geometry of de Sitter space and properties of quantum field theory on de Sitter space, especially the temperature and entropy of de Sitter space. The final lecture contains a pedagogical discussion of the appearance of

In mathematics and physics, n-dimensional anti-de Sitter space is a maximally symmetric Lorentzian manifold with constant negative scalar curvature. Anti-de Sitter space and de Sitter space are named after Willem de Sitter, professor of astronomy at Leiden University and director of the Leiden Observatory. Willem de Sitter and Albert Einstein worked together closely in Leiden in the 1920s on the spacetime structure of the universe.

And when the cosmological constant is negative, you get AdS space-time, which has a saddle shape.

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]. De Sitter space can also be defined as the quotient O(1, n) / O(1, n − 1) of two indefinite orthogonal groups, which shows that it is a non-Riemannian symmetric space.

Sitter space and anti-de Sitter space are thus simply related. Note also that, appearances notwithstanding, there is nothing special about the waist, since adSn is in fact a homogeneous space having n(n+1)/2 Killing vectors that generate the group SO(n−1,2). The …

(8) We can draw a picture of a two dimensional anti-de Sitter space, which is a 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 . 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.

Share. as Schwarzschild black holes in asymptotically anti-de Sitter (AdS) space, it is often di cult to say what it means to be behind the horizon in the dual theory. A possible alternative approach is to consider string theory in the near horizon geometry of a black hole. The latter takes the form AdS 2 S2 for extremal black holes in four dimensions.
