Abstract
It is shown that a recently proposed field-theoretic model of Anderson localization has the same critical behavior as that found in te problem of branched polymers. THus this model in D dimensions is in the same universality class as that studied by Parisi and Sourlas, which includes the Yang-Lee edge singularity in D minus 2 dimensions. It is stressed that critical properties can be studied either at constant order parameter or at constant field and that critical exponents in the two cases are related by a Fisher renormalization. It is noted that constant order parameter exponents diverge at a critical dimension D//c.
