The local structure of spacetime on ghost-free bimetric theory
  KTH/Nordita/SU seminar in Theoretical Physics

Wednesday 07 December 2016
from 11:00 to 12:00
at A4:1069
Speaker : Mikica Kokic (Fysikum, SU)
Abstract : The major concern in any modified theory of gravity is about its consistency. The absence of ghosts in bimetric theory is ensured by the special form of the interaction term that is based on the matrix square root function of the two metric fields combined. In this talk we present the theorem which connects this square root also with the local causality and highlight its role in empowering the field dynamics of the theory to be predictive.
