in this paper, a boussinesq equation is solved by using the adomian's decomposition method, modified adomian's decomposition method and homotopy analysis method. the approximate solution of this equation is calculated in the form of series which its components are computed by applying a recursive relation. the existence and uniqueness of the solution and the convergence of the propose...

in this article, a numerical approximation to the solution of the newell-whitehead equation (nwe) and cauchy problem of ill-posed non-linear diffusion equation have been studied. the presented scheme is obtained by using the derivative of the cubic b-spline quasi-interpolation (bsqi) to approximate the spatial derivative of the dependent variable and first order forward difference to approximat...

We consider the problem of approximate solution e x of a linear system Ax = b over the reals, such that kAe x ? bk kbk; for a given ; 0 < < 1: This is one of the most fundamental of all computational problems. Let (A) = kAkkA ?1 k be the condition number of the n n input matrix A. Sparse, diagonally dominant (DD) linear systems appear very frequently in the solution of linear systems associated...
