Efficient construction of contact coordinates for partial prolongations
Peter J. Vassiliou
Let $\CV$ be a vector field distribution on manifold . We give an efficient algorithm for the construction of local coordinates on such that $\CV$ may be locally expressed a…

A constructive generalised Goursat normal form
Peter J. Vassiliou
We provide necessary and sufficient conditions on the derived type of a vector field distribution $\Cal V$ in order that it be locally equivalent to a partial prolongation of the c…

Mass and 3-metrics of non-negative scalar curvature
Robert Bartnik
Physicists believe, with some justification, that there should be a correspondence between familiar properties of Newtonian gravity and properties of solutions of the Einstein equa…
