Nonclassical Approximate Symmetries of Evolution Equations with a Small Parameter
We introduce a method of approximate nonclassical Lie-B\"acklund symmetries
for partial differential equations with a small parameter and discuss
applications of this method to finding of approximate solutions both integrable
and nonintegrable equations.Comment: Published in SIGMA (Symmetry, Integrability and Geometry: Methods and
