With the inclusion of the effects of interface capillary waves, the lower critical dimension has recently been shown to be 3. This paper contains a detailed derivation of the interface model, with the use of the replica method. Based on this model we then present a detailed discussion of a renormalization-group calculation in d=3+ dimensions. © 1982 The American Physical Society.
