Einstein's Equations with Asymptotically Stable Constraint Propagation
Othmar Brodbeck, Simonetta Frittelli, Peter Huebner +1
We introduce a proposal to modify Einstein's equations by embedding them in a larger symmetric hyperbolic system. The additional dynamical variables of the modified system are esse…

On the dynamics of Einstein's equations in the Ashtekar formulation
Mirta S. Iriondo, Enzo O. Leguizamon, Oscar A. Reula
We study the dynamics of Einstein's equations in Ashtekar's variables from the point of view of the theory of hyperbolic systems of evolution equations. We extend previous results…
