SUMMARY:Well-posed initial value formulation of general effective field th
 eories of gravity - Aron Kovacs\, Queen Mary University of London

DESCRIPTION:In this talk\, I will show that all higher-derivative effectiv
 e field theories (EFTs) of vacuum gravity admit a well-posed initial value
  formulation when augmented by suitable regularising terms. These regulari
 sing terms can be obtained by field redefinitions and do not affect the dy
 namics in the regime of validity of EFT. I will explain how our result app
 lies to the quadratic\, cubic\, and quartic truncations of the EFT of grav
 ity and to various truncations of a simple EFT of a scalar field. Finally\
 , I will also discuss some numerical results on the non-linear dynamics of
  this simple scalar field theory.
