Ashtekar Variables in Classical General Relativity

The task I was given for this lecture is to present Ashtekar’s connection variables for classical General Relativity in a pedagogical manner. My intention is to describe a possible route towards a reformulation of General Relativity in terms of Ashtekar’s connection variables. I try to give self-contained and hopefully painless derivations of the crucial steps, without entering too much into th...

Spin half in classical general relativity

It is shown that models of elementary particles in classical general relativity will naturally have the transformation properties of a spinor if the spacetime manifold is not time orientable. From a purely pragmatic interpretation of quantum theory this explains why spinors are needed to represent particles. The models are based entirely on classical general relativity and are motivated by the ...

No Time Machines in Classical General Relativity

Irrespective of local conditions imposed on the metric, any extendible spacetime U has a maximal extension containing no closed causal curves outside the chronological past of U. We prove this fact and interpret it as impossibility (in classical general relativity) of the time machines, insofar as the latter are defined to be causality-violating regions created by human beings (as opposed to th...

Topology Change in Classical General Relativity

This paper clarifies some aspects of Lorentzian topology change, and it extends to a wider class of spacetimes previous results of Geroch and Tipler that show that topology change is only to be had at a price. The scenarios studied here are ones in which an initial spacelike surface is joined by a connected “interpolating spacetime” to a final spacelike surface, possibly of different topology. ...

Some Recent Progress in Classical General Relativity

One of the most difficult problems in classical relativity is to understand how and when singularities form. In the 1960’s, Hawking and Penrose proved that the existence of a closed trapped surface in an asymptotically flat spacelike hypersurface gives rise to a singularity in space-time. However, no proof based on pure partial differential equation arguments was found, and many questions remai...
