Variable coefficient Davey-Stewartson system with a Kac-Moody-Virasoro symmetry algebra
F. Güngör, C. Özemir
We study the symmetry group properties of the variable coefficient Davey-Stewartson (vcDS) system. The Lie point symmetry algebra with a Kac-Moody-Virasoro (KMV) structure is shown…

Symmetries of 2+1-dimensional variable coefficient Burgers equations
F. Güngör, C. Özemir
We consider a class of variable coefficient Burgers equations in 2+1 dimensions and make use of their equivalence group to give a complete symmetry classification up to equivalence…
