On Waylen's regular axisymmetric similarity solutions
Edward D. Fackerell, David Hartley
We review the similarity solutions proposed by Waylen for a regular time-dependent axisymmetric vacuum space-time, and show that the key equation introduced to solve the invariant…

Tensor distributions on signature-changing space-times
David Hartley, Robin W. Tucker, Philip A. Tuckey +1
Irregularities in the metric tensor of a signature-changing space-time suggest that field equations on such space-times might be regarded as distributional. We review the formalism…

Normal frames for non-Riemannian connections
David Hartley
The principal properties of geodesic normal coordinates are the vanishing of the connection components and first derivatives of the metric components at some point. It is well-know…
