We propose that space-time at the smallest scales is in reality a causal set: a locally finite set of elements endowed with a partial order corresponding to the macroscopic relation that defines pastExpand

Quantum source of entropy for black holes.
We associate to any quantum field propagating in the background metric of a black hole an effective density matrix whose statistical entropy can be interpreted as a contribution to the total entropyExpand

Time as spacetime four-volume and the Ashtekar variables.
We consider a recently proposed theory of gravity, classically equivalent to Einstein's theory with the cosmological constant as an additional variable, in which spacetime volume plays the role ofExpand

Chaos in Robertson-Walker
Chaos in Robertson-Walker cosmological models where gravity is coupled to one or more scalar elds has been studied by a few authors, mostly using numerical simulations. In this paper we begin aExpand
