Query: Dimensional Reduction for Fermions   We generalize the concept of dimensional reduction to operators involving
fermion fields in high temperature field theories. It is found that the
ultraviolet behavior of the running coupling constant plays a crucial role. The
general concept is illustrated explicitly in the Gross-Neveu model.
