Continuum modes of nonlocal field theories
We study a class of nonlocal Lorentzian quantum field theories, where the d'Alembertian operator “box” is replaced by a non-analytic function of the d'Alembertian, f (“box”). This is inspired by the Causal Set program where such an evolution arises as the continuum limit of a wave equation...
