A scaled characteristics method for the asymptotic solution of weakly nonlinear wave equations. <i>Electronic Journal of Differential Equations, 1998</i>(03), pp. 1-10.1072-6691https://hdl.handle.net/10877/7928We formulate a multi-scale perturbation technique to asymptotically solve weakly nonlinear hyperbolic equations. The method is based on a set of scaled characteristic coordinates. We show that this technique leads to a simplified system of ordinary differential equations describing the weakly nonlinear interaction between left and right running waves. Using this method, a uniformly valid first order solution of a prototype nonlinear equation is derived.Text10 pages1 file (.pdf)enAttribution 4.0 InternationalMultiple scalePerturbationNonlinearWavesArticle
