Classical sequential growth dynamics for causal sets

- D. Rideout, R. Sorkin
- Physics
- 25 April 1999

Starting from certain causality conditions and a discrete form of general covariance, we derive a very general family of classically stochastic, sequential growth dynamics for causal sets. The… Expand

Towards standard testbeds for numerical relativity

- M. Alcubierre, G. Allen, +18 authors J. Winicour
- Physics
- 1 April 2003

In recent years, many different numerical evolution schemes for Einstein's equations have been proposed to address stability and accuracy problems that have plagued the numerical relativity community… Expand

Evidence for a continuum limit in causal set dynamics

- D. Rideout, R. Sorkin
- Physics
- 31 March 2000

We find evidence for a continuum limit of a particular causal set dynamics which depends on only a single ``coupling constant'' p and is easy to simulate on a computer. The model in question is a… Expand

Indications of de Sitter Spacetime from Classical Sequential Growth Dynamics of Causal Sets

- Maqbool Ahmed, D. Rideout
- Physics
- 25 September 2009

A large class of the dynamical laws for causal sets described by a classical process of sequential growth yields a cyclic universe, whose cycles of expansion and contraction are punctuated by single… Expand

General solution for classical sequential growth dynamics of causal sets

- M. Varadarajan, D. Rideout
- Physics
- 15 April 2005

A classical precursor to a full quantum dynamics for causal sets has been formulated in terms of a stochastic sequential growth process in which the elements of the causal set arise in a sort of… Expand

Spacelike distance from discrete causal order

- D. Rideout, P. Wallden
- Physics
- 9 October 2008

Any discrete approach to quantum gravity must provide some prescription as to how to deduce continuum properties from the discrete substructure. In the causal set approach it is straightforward to… Expand

Dynamics of causal sets

- D. Rideout
- Physics
- 14 December 2002

The Causal Set approach to quantum gravity asserts that spacetime, at its smallest length scale, has a discrete structure. This discrete structure takes the form of a locally finite order relation,… Expand

Spatial hypersurfaces in causal set cosmology

- S. Major, D. Rideout, S. Surya
- Physics
- 29 June 2005

Within the causal set approach to quantum gravity, a discrete analogue of a spacelike region is a set of unrelated elements, or an antichain. In the continuum approximation of the theory, a… Expand
