Resumen:
We investigate divergence-type theories describing the dissipative
interaction between a field and a fluid. We look for theories which,
under equilibrium conditions, reduce to the theory of a Klein-Gordon
scalar field and a perfect fluid. We show that the requirements of
causality and positivity of entropy production put nontrivial
constraints to the structure of the interaction terms. These theories
provide a basis for the phenomonological study of the reheating period.
