Weak Transversality and Partially Invariant Solutions
A. M. Grundland, P. Tempesta, P. Winternitz
Abstract
New exact solutions are obtained for several nonlinear physical equations, namely the Navier-Stokes and Euler systems, an isentropic compressible fluid system and a vector nonlinear Schroedinger equation. The solution methods make use of the symmetry group of the system in situations when the standard Lie method of symmetry reduction is not applicable.
