No Quantum Super-Minisuperspace with
Riccardo Capovilla, Octavio Obregon
We show that the quantum super-minisuperspace of N=1 supergravity with has no non-trivial physical states for class A Bianchi models. Hence, in super quantum cosmology, t…

No New Symmetries of the Vacuum Einstein Equations
Riccardo Capovilla
In this note we examine some recently proposed solutions of the linearized vacuum Einstein equations. We show that such solutions are {\it not} symmetries of the Einstein equations…

Non-Minimally Coupled Scalar Field and Ashtekar Variables
Riccardo Capovilla
The non-minimal coupling of a scalar field is considered in the framework of Ashtekar's new variables formulation of gravity. A first order action functional for this system is der…
