Title
Symmetries for initial value problems
RIS ID
84635
Abstract
In this letter we give a less restrictive condition compared to that given by Zhang and Chen (2010), for first order initial conditions to be recoverable with a particular classical or nonclassical symmetry generator. Examples are provided for the generalised Kuramoto-Sivashinsky equation and a nonlinear diffusion equation with a sink term.
