  1. 81. General relativity, Gravity and the discovery of gravitational waves
    Prof. Fawad Hassan (Stockholm University)

    Gravitation and Gravitational Waves
    Invited

    I will motivate the study of theories of gravity in the presence of extra spin-2 fields and will then describe a ghost free bimetric theory of gravity, some of its physical implications, and the current status of the theory. In particular, I will focus on the notions of space and time in the theory in the presence of two metric fields.

  2. 105. Bimetric gravity and analysis of constraints

    Gravitation and Gravitational Waves
    Invited

    In bimetric gravity, a number of constraints are needed to ensure that the theory is free of ghosts and propagates the appropriate number of degrees of freedom. I will describe my recent work analyzing the origin and structure of these constraints. The ghost free bimetric theory has six constraints, four of which are first class and are associated with the diffeomorphism invariance of the...
