Abstract

We embed the Teichmüller space of the once punctured torus T(1,1) into the set of conjugacy classes of groups generated by three anti-holomorphic involutions I1, I2 and I3 (Lagrangian triangle groups), acting on the complex hyperbolic plane . We deform this embedding, and obtain a three dimensional family E of discrete, faithful and type preserving representations of the fundamental group of the once punctured torus.
