A (2+1)-dimensional KdV equation and mKdV equation: symmetries, group invariant solutions and conservation laws
2019
Abstract In this paper, we analyse the (2+1)-dimensional KdV and mKdV equations. Firtly, on the basis of the extended Lax pair, we derive these equations. Thereafter, the symmetry generators are determined followed by the application of the mCK method. Finally, conservation laws (including higher order) are studied.
