Classical GR as a topological theory with linear constraints
Classical GR topological theory
2010/12/27
We investigate a formulation of continuum 4d gravity in terms of a constrained topological (BF) theory, in the spirit of the Plebanski formulation, but involving only linear constraints, of the type ...
Scalar models for the generalized Chaplygin gas and the structure formation constraints
Scalar models the generalized Chaplygin gas
2010/12/24
The generalized Chaplygin gas model represents a tentative to unify dark matter and dark energy. It is characterized by a fluid with an equation of state $p = - A/\rho^\alpha$. It can be obtained fro...
Relativistic Constraints for a Naturalistic Metaphysics of Time
Relativistic Constraints Naturalistic Metaphysics of Time
2010/11/16
The traditional metaphysical debate between static and dynamic views in the philosophy of time is examined in light of considerations concerning the nature of time in physical theory. Adapting the fo...
