Gravitational action with null boundaries

- L. Lehner, R. Myers, E. Poisson, R. Sorkin
- Physics
- 1 September 2016

The present paper provides a complete treatment of boundary terms in general relativity to include cases with lightlike boundary segments along with the usual spacelike and timelike ones.… Expand

QUANTUM MECHANICS AS QUANTUM MEASURE THEORY

- R. Sorkin
- Physics
- 7 January 1994

The additivity of classical probabilities is only the first in a hierarchy of possible sum rules, each of which implies its successor. The first and most restrictive sum rule of the hierarchy yields… Expand

Classical sequential growth dynamics for causal sets

- D. P. 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

Finitary substitute for continuous topology

- R. Sorkin
- Mathematics
- 1 July 1991

Finite topological spaces are combinatorial structures that can serve as replacements for, or approximations to, bounded regions within continuous spaces such as manifolds. In this spirit, the… Expand

Kaluza-Klein Monopole

- R. Sorkin
- Physics
- 11 July 1983

By adding the trivial term $\ensuremath{-}d{t}^{2}$ one can convert the four-dimensional (positive-definite) Newman-Unti-Tamburino line element into a static solution of the five-dimensional vacuum… Expand

Causal sets: Discrete gravity

- R. Sorkin
- Mathematics
- 2005

These are some notes in lieu of the lectures I was scheduled to give, but had to cancel at the last moment. In some places, they are more complete, in others much less so, regrettably. I hope they at… Expand

Signal-detection analysis of group decision making.

How effectively can groups of people make yes-or-no decisions? To answer this question, we used signal-detection theory to model the behavior of groups of human participants in a visual detection… Expand

Quantum Measure Theory and its Interpretation

- R. Sorkin
- Computer Science, Physics
- 30 July 1995

We propose a realistic, spacetime interpretation of quantum theory in which reality constitutes a *single* history obeying a "law of motion" that makes definite, but incomplete, predictions about its… Expand

Quantum dynamics without the wavefunction

- R. Sorkin
- Physics, Mathematics
- 24 October 2006

When suitably generalized and interpreted, the path integral offers an alternative to the more familiar quantal formalism based on state vectors, self-adjoint operators and external observers.… Expand

An exercise in "anhomomorphic logic"

- R. Sorkin
- Mathematics, Physics
- 30 March 2007

A classical logic exhibits a threefold inner structure comprising an algebra of propositions , a space of "truth values" V, and a distinguished family of mappings from propositions to truth values.… Expand
