Dressing Transformations and the Algebraic--Geometrical Solutions in the   Conformal Affine $sl(2)$ Toda Model
  It is shown that the algebraic--geometrical (or quasiperiodic) solutions of the Conformal Affine $sl(2)$ Toda model are generated from the vacuum via dressing transformations. This result generalizes the result of Babelon and Bernard which states that the $N$--soliton solutions are generated from the vacuum by dressing transformations.
