Mathematics, Vol. 5, Pages 59: Invariant Solutions for a Class of Perturbed Nonlinear Wave Equations
Mathematics doi: 10.3390/math5040059
Approximate symmetries of a class of perturbed nonlinear wave equations are computed using two newly-developed methods. Invariant solutions associated with the approximate symmetries are constructed for both methods. Symmetries and solutions are compared through discussing the advantages and disadvantages of each method.
