Classical and Quantum Theory of Perturbations in Inflationary Universe Models
R. Brandenberger, H. Feldman, V. Mukhanov
A brief introduction to the gauge invariant classical and quantum theory of cosmological perturbations is given. The formalism is applied to inflationary Universe models and yields…
A Nonsingular Two Dimensional Black Hole
M. Trodden, V. Mukhanov, R. Brandenberger
We construct a model of gravity in 1+1 spacetime dimensions in which the solutions approach the Schwarzschild metric at large and de Sitter space far inside the horizon. Our mo…
A Cosmological Theory without Singularities
R. Brandenberger, V. Mukhanov, A. Sornborger
A theory of gravitation is constructed in which all homogeneous and isotropic solutions are nonsingular, and in which all curvature invariants are bounded. All solutions for which…
