  We analyze bimolecular reactions that proceed by a long-ranged reactive
interaction, using a field theoretic approach that takes into account
fluctuations.
  We consider both the one-species, $A+A \to \emptyset$ reaction and the
two-species, $A+B \to \emptyset$ reaction. We consider both mobile and immobile
reactants, both in the presence and in the absence of adsorption.
