Causality, shocks and instabilities in vector field models of Lorentz symmetry breaking
M. A. Clayton
We show that that vector field-based models of the ether generically do not have a Hamiltonian that is bounded from below in a flat spacetime. We also demonstrate that these models…

Issues in Quantum-Geometric Propagation
M. A. Clayton
A discussion of relativistic quantum-geometric mechanics on phase space and its generalisation to the propagation of free, massive, quantum-geometric scalar fields on curved spacet…

The Initial-Value Problem of Spherically Symmetric Wyman Sector Nonsymmetric Gravitational Theory
M. A. Clayton, L. Demopoulos, J. Legare
We cast the four-dimensional field equations of the Nonsymmetric Gravitational Theory (NGT) into a form appropriate for numerical study. In doing so, we have restricted ourselves t…
