A coherent approach to Spacetime Foam
Remo Garattini
A coherent superposition of N Schwarzschild wormholes is proposed as a model for spacetime foam. Following the subtraction procedure for manifolds with boundaries, we calculate by…
Wormholes and Spacetime Foam: an approach to the Cosmological Constant and Entropy
Remo Garattini
This paper summarizes the contribution presented at the IX Marcel Grossmann Meeting (Rome, July 2000). A simple model of spacetime foam, made by Schwarzschild wormholes in a se…
On the existence of nontrivial solutions for a nonlinear equation relative to a measure-valued Lagrangian on homogeneous spaces
Remo Garattini
We prove the existence of a non-trivial solution for a nonlinear equation related to a measure-valued Lagrangian. The result is based on a compact embedding theorem of the Lagrangi…
Casimir energy and variational methods in AdS spacetime
Remo Garattini
Following the subtraction procedure for manifolds with boundaries, we calculate by variational methods, the Schwarzschild-Anti-de Sitter and the Anti-de Sitter space energy differe…
A Spacetime Foam Approach to the Schwarzschild-de Sitter Entropy
Remo Garattini
The entropy for a black hole in a de Sitter space is approached within the framework of spacetime foam. A simple model, made by wormholes in a semiclassical approximation, is t…
A Spacetime Foam approach to the cosmological constant and entropy
Remo Garattini
A simple model of spacetime foam, made by wormholes in a semiclassical approximation, is taken under examination. The Casimir-like energy of the quantum fluctuation of such a m…
