| title =  Nontrivial 1-parameter families of zero-curvature representations obtained via symmetry actions
| abstract = We will discuss the problem of constructing a 1-parameter family <math>\alpha_{\lambda}</math> of zero-curvature representations of an equation <math>\mathcal E</math>, by means of classical symmetry actions on a given zero-curvature representation <math>\alpha</math>.  By using the cohomology defined by the horizontal gauge differential of <math>\alpha</math>, we provide an infinitesimal criterion which permits to identify all infinitesimal classical symmetries of <math>\mathcal E</math> whose flow could be used to embed <math>\alpha</math> into a nontrivial 1-parameter family <math>\alpha_{\lambda}</math> of zero-curvature representations of <math>\mathcal E</math>.  The results are illustrated with some examples.
