Two-dimensional Haar Wavelet Method for Numerical Solution of Delay Partial Differential Equations
In this paper, a two-dimensional Haar wavelet collocation method is applied to obtain the numerical solution of delay and neutral delay partial differential equations. Both linear and nonlinear problems can be solved using this method.
