Diffusive inflationary cosmology
Journal of Geometry and Physics, 1990The author considers the Ricci flow equation \(g'(t)=-2k Ric(g(t))+Dg(t)\) for a Riemannian metric g(t) on a compact 3-manifold, where k and D are some constants. This is related to general relativity by considering a corresponding Lorentzian metric \(^{(4)}g=-c^ 2dt^ 2+g(t).\) For metrics of this form, Einstein's vacuum field equation with ...

Developments in inflationary cosmology
Pramana, 2009This talk presents some recent work that has been done in inflationary cosmology. First a brief review is given of the inflation scenario and its basic models. After that, one of the main problems in developing inflationary models has been the requirement of a very flat inflation potential. In solving this problem, supersymmetry has played a major role,
