On The Equivalence of the FRW Field Equations and those of Newtonian Cosmology
Clive G. Wells
We present a simple argument to explain why the field equations of the Friedmann-Robertson-Walker metric are equivalent to those of Newtonian cosmology. By passing to the infinite…
A stochastic approximation scheme and convergence theorem for particle interactions with perfectly reflecting boundaries
Clive G. Wells
We prove the existence of a solution to an equation governing the number density within a compact domain of a discrete particle system for a prescribed class of particle interactio…
The Adiabatic Invariance of the Action Variable in Classical Dynamics
Clive G. Wells, Stephen T. C. Siklos
We consider one-dimensional classical time-dependent Hamiltonian systems with quasi-periodic orbits. It is well-known that such systems possess an adiabatic invariant which coincid…
Extending the Black Hole Uniqueness Theorems, II. Superstring Black Holes
Clive G. Wells
We make use of an internal symmetry of a truncation of the bosonic sector of the superstring and N=4 supergravity theories to write down an analogue of Robinson's identity for the…
Classical and Quantum Initial Value Problems for Models of Chronology Violation
C. J. Fewster, A. Higuchi, C. G. Wells
We study the classical and quantum theory of a class of nonlinear differential equations on chronology violating spacetime models in which space consists of finitely many discrete…
Unitarity of Quantum Theory and Closed Time-Like Curves
C. J. Fewster, C. G. Wells
Interacting quantum fields on spacetimes containing regions of closed timelike curves (CTCs) are subject to a non-unitary evolution . Recently, a prescription has been proposed,…
