In this paper, we study nonmaximal representations of surface groups in PU(2,1). We show the existence in genus large enough, of convex-cocompact representations of nonmaximal Toledo invariant admitting a unique equivariant minimal surface, which is holomorphic and of second fundamental form arbitrarily small. These examples can be obtained for any Toledo invariant of the form 2-2g+(2/3)d, provided g is large compared to d. When d is not divisible by 3, this yields examples of convex-cocompact representations in PU(2,1) which do not lift to SU(2,1). |
