Einstein manifolds in Ashtekar variables: explicit examples
Lay Nam Chang, Chopin Soo
We show that all solutions to the vacuum Einstein field equations may be mapped to instanton configurations of the Ashtekar variables. These solutions are characterized by properti…

Brst Cohomology and Invariants of 4D Gravity in Ashtekar Variables
Lay Nam Chang, Chopin Soo
We discuss the BRST cohomologies of the invariants associated with the description of classical and quantum gravity in four dimensions, using the Ashtekar variables. These invarian…
