Abstract: (Springer)
We present the shock-free wave propagation requirements for massless fields.First, we briefly argue how the “completely exceptional” approach, originallydeveloped to study the characteristics of hyperbolic systems in 1 + 1 dimensions,can be generalized to higher dimensions and used to describe propagation withoutemerging shocks, with characteristic flow remaining parallel along the waves.We then study the resulting requirements for scalar, vector, vector-scalar, andgravity models and characterize physically acceptable actions in each case.
