“…This method has been systematically studied for linear partial differential equations [1,12,13,21,22], however very few works have been done to solve nonlinear partial differential equations [3][4][5]. It is also observed that the operational matrix wavelet methods for the non linear partial differential equations in the recent literature fall into two groups: methods for initial value problems [14,24] and the methods for initial and boundary value problems [3][4][5][6]15,17]. By assuming the existence and uniqueness of solution as well as the convergence of the quasilinearization scheme, classical quasilinearization based operational matrix wavelet method for various types of ordinary and partial differential equations are studied in [7][8][9][17][18][19] and [3,5,6,10,15], respectively.…”
