Abstract
We discuss a possible superconducting state in UPt3 group-theoretically. It is shown that the antiferromagnetic fluctuations favor a singlet state by using a real space approach. Analysis of experiments shows that the coupling between the antiferromagnetism and superconductivity is small for URu2Si2 while fairly large for UPt3.
