For a free group F, there is a natural action of Out(F) on the space of representations Hom(F,PSL(2,C)). Minsky introduced an open subset PS(F) (for primitive stable representations) on which Out(F) acts properly discontinuously which is expected to be maximal. I will explain the definition of this set PS(F) and introduce examples and properties of primitive stable representations with discrete image.
