Linear Problems Associated with Evolution Equations of the Type utt = F(u, ux, uxx, ut)
Evolution equations which describe pseudospherical surfaces are considered. A systematic procedure to determine a linear problem for which a given equation is the integrability condition is obtained. The theory is applied to families of equations. In particular, the Liouville equation is obtained as the integrability condition of a linear problem.
