Tensor distributions on signature-changing space-times (1997)

Hartley, David, Tucker, Robin W., Tuckey, Philip A., Dray, Tevian

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 of tensor...
