On the Cauchy problem in Effective Field Theories of gravity
Effective field theory provides a way of parameterizing strong-field deviations from General Relativity that might be observable in the gravitational waves emitted in a black hole merger. To perform numerical simulations of black hole mergers in such theories it is necessary that the equations be written in a form that admits a well-posed initial value formulation. In this talk, I will discuss recent progress in the initial value formulation of effective theories of gravity, as well as some open problems.
