We describe a general method of obtaining nonlinear models possessing either topological or nontopological classical solutions. In particular, the program can be carried out when the so-called stability equations are derived from group-theoretical arguments. Using Schrödinger-like equations with Pöschl-Teller potential, which is related to SU(2), we obtain interesting field theories labeled by a natural number l. We also consider Rosen-Morse potential, which is related to SL (2, C), getting a new family of models. Previously known examples, such as sine-Gordon, Φ4 and Liouville theory, are obtained in this context.
