Seminars
Seminar “Modern Mathematical Physics”
Date and Time: Thursday, 7 December 2017, at 2:30 PM
Venue: Blokhintsev Hall (4th floor), Bogoliubov Laboratory of Theoretical Physics
Seminar Topic: «Standard Cosmology Delayed»
Speaker: Anjan Ananda Sen (Center For Theoretical Physics, Jamia Millia Islamia Central University, New Delhi, India)
Abstract:
The introduction of a delay in the Friedmann equation of cosmological evolution is shown to result in the very early universe undergoing the necessary accelerated expansion in the usual radiation (or matter) dominated phase. Occurring even without a violation of the strong energy condition, this expansion slows down naturally to go over to the decelerated phase, namely the standard Hubble expansion. This may obviate the need for a scalar field driven inflationary epoch.
The theme participants and everybody interested are kindly invited!
