We introduce a new type of recursion operator suitable to generate a class of nonlocal symmetries for those second-order evolution equations in 1+1 dimension which allow the complete integration of their time-independent versions. We show that this class of evolution equations is C-integrable (linearizable by a point transformation). We also discuss some applications.

Abstract
We introduce a new type of recursion operator suitable to generate a class of nonlocal symmetries for those second-order evolution equations in 1+1 dimension which allow the complete integration of their time-independent versions. We show that this class of evolution equations is C-integrable (linearizable by a point transformation). We also discuss some applications.File in questo prodotto:
