Chaos, decoherence and quantum cosmology
E Calzetta - Classical and quantum gravity, 2012 - iopscience.iop.org
In this topical review we discuss the connections between chaos, decoherence and
quantum cosmology. We understand chaos as classical chaos in systems with a finite …

Given a Lorentzian spacetime $(M, g) $ and a non-vanishing timelike vector field $ u
(\lambda) $ with level surfaces $\Sigma $, one can construct on $ M $ a Euclidean metric …

Euclidean action and the Einstein tensor
D Kothawala - Physical Review D, 2018 - APS
We give a local description of the Euclidean regime (M, g, u) of Lorentzian spacetimes (M, g)
based on timelike geodesics u passing through an arbitrary event p 0∈ M. We show that, to …
