Symmetries and Exact Solutions of a 2+1-dimensional Sine-Gordon System
P. A. Clarkson, E. L. Mansfield, A. E. Milne
We investigate the classical and nonclassical reductions of the -dimensional sine-Gordon system of Konopelchenko and Rogers, which is a strong generalisation of the sine-Gordo…
Symmetry Reductions and Exact Solutions of Shallow Water Wave Equations
Peter A. Clarkson, Elizabeth L. Mansfield
In this paper we study symmetry reductions and exact solutions of the shallow water wave (SWW) equation $$u_{xxxt} + αu_x u_{xt} + βu_t u_{xx} - u_{xt} - u_{xx} = 0,\eqno(1)$$ wher…
On a Shallow Water Wave Equation
Peter A. Clarkson, Elizabeth L. Mansfield
In this paper we study a shallow water equation derivable using the Boussinesq approximation, which includes as two special cases, one equation discussed by Ablowitz et. al. [Stud.…
Algorithms for the Nonclassical Method of Symmetry Reductions
Peter A. Clarkson, Elizabeth L. Mansfield
In this article we present first an algorithm for calculating the determining equations associated with so-called ``nonclassical method'' of symmetry reductions (a la Bluman and Co…
