Generalized symmetry reduction of nonlinear differential equations
I. M. Tsyfra, W. Rzeszut, V. A. Vladimirov
We study the application of generalized symmetry for reducing nonlinear partial differential equations. We construct the ansatzes for dependent variable which reduce the scalar…

On a reduction of nonlinear evolution and wave type equations via non-point symmetry method
Ivan Tsyfra
We study the symmetry reduction of nonlinear evolution and wave type differential equations by using operators of non-point symmetry. In our approach we use both operators of class…
