TI - Approximate Symmetries of the Harry Dym Equation
SP - 109170
VL - 2013
AB - We derive the first-order approximate symmetries for the Harry Dym equation by the method of approximate transformation groups proposed by Baikov et al. (1989, 1996). Moreover, weinvestigate the structure of the Lie algebra of symmetries of the perturbed Harry Dym equation. We compute the one-dimensional optimal system of subalgebras as well as point out some approximately differential invariantswith respect to the generators of Lie algebra and optimal system.
