On the other hand there are many flat tori isometrically immersed in S3 with nonconstant mean curvature. In this paper we deal with isometric deformations of these surfaces. To state the result we recall the notion of congruence of immersions. For i=1,2, let fi:Xi• ̈Y be an immersion of a smooth manifold Xi into a Riemannian manifold Y. The immersions fl and f2 are said to be congruent if there exist an isometry A:Y• ̈Y and a diffeomorphism •¬ such that •¬ We shall write f1=f2 if f1 and f2 are congruent. The main result of this paper is the following theorem.
