Approximate Symmetries of Wave Equations | |
Baikov V. A., Gazizov R. K. Ufa State Aviation Techinical University, Ufa, RUSSIA Ibragimov N. H. The University of North West, Mmabato, SOUTH AFRICA In this work we briefly present the theory of approximate transformation groups which let us constructively find approximate symmetries and approximately invariant solutions of equations with a small parameter. The theory is applied to large classes of evolution and wave equations. |
