A New Family of Gauges in Linearized General Relativity

Giampiero Esposito, Cosimo Stornaiolo

For vacuum Maxwell theory in four dimensions, a supplementary condition exists (due to Eastwood and Singer) which is invariant under conformal rescalings of the metric, in agreemen…

Oscillating universes as eigensolutions of cosmological Schrödinger equation

S. Capozziello, A. Feoli, G. Lambiase

We propose a cosmological model which could explain, in a very natural way, the apparently periodic structures of the universe, as revealed in a series of recent observations. Our…

Non-Local Boundary Conditions in Euclidean Quantum Gravity

Giampiero Esposito

Non-local boundary conditions for Euclidean quantum gravity are proposed, consisting of an integro-differential boundary operator acting on metric perturbations. In this case, the…

Cosmological perturbations in singularity-free, deflationary models

S. Capozziello, G. Lambiase, G. Scarpetta

We consider scalar perturbations of energy-density for a class of cosmological models where an early phase of accelerated expansion evolves, without any fine-tuning for graceful ex…

String Dilaton Fluid Cosmology

S. Capozziello, G. Lambiase, R. Capaldo

We investigate -dimensional string-dilaton cosmology with effective dilaton potential in presence of perfect-fluid matter.We get exact solutions parametrized by the constant…
