Spinorial coordinates for Lorentzian 4-metrics
D. C. Robinson
Lorentzian 4-metrics are expressed in spinorial coordinates. In these coordinates the metric components can be factorized into a product of complex conjugate quantities. The linear…

Generalized Chern-Simons action principles for gravity
D. C. Robinson
Generalized differential forms are employed to construct generalized connections. Lorentzian four-metrics determined by certain of these connections satisfy Einstein's vacuum field…
