ITMP Seminar "Constrained modified gravities: generalized unimodular gravity and beyond"

ITMP Seminar
21 September 2020

Dear Colleagues,

We are pleased to announce that the next ITMP seminar will be held on Wednesday, September 23, at 18:00. The seminar will be arranged via Zoom. Please, find below the seminar information as well as information required for joining the meeting via Zoom.

 

Speaker: Nikita Kolganov, ITMP

Topic: Constrained modified gravities: generalized unimodular gravity and beyond

Abstract: In my talk, I will give you a brief introduction into modified gravity theories, and then I will proceed to particular modified gravity models, which I'm interested in. Most of the modified gravities are equivalent to the General Relativity, equipped with some additional degrees of freedom. In our case these d.o.f. are obtained by the explicit breaking of general covariance by an algebraic constraint on metric coefficients. I'm going to discuss the covariantization issue of such theories, its duality to well-known k-essence and self-gravitating media models, and applications to inflationary cosmology.

 

If you want to join the seminar please register here before 14:00, September 23.
