In 1988, Parker and Sochacki announced a theorem which proved that the Picard iteration, properly modified, generates the Taylor series solution to any ordinary differential equation (ODE) on n with a polynomial generator. In this paper, we present an analogous theorem for partial differential equations (PDEs) with polynomial generators and analytic initial conditions. Since the domain of a sol...

In this paper, we present an approximate numerical solution to the well known Michaelis-Menten nonlinear biochemical reaction system using a stochastic technique based on hybrid polynomial basis evolutionary computing. The approximate solution is expanded as a linear combination of polynomial basis with unknown parameters. The system of nonlinear differential equation is transformed into an equ...

Abstract The Picard iteration method is used to study the existence and uniqueness of solutions for stochastic Volterra-Levin equation with variable delays. Several sufficient conditions are specified ensure that has a unique solution. First, transformed into an integral equation. Then, obtain solution equation, successive approximation sequences constructed, derived by convergence sequences. F...

In this paper we demonstrate that a number of fixed point iteration problems can be solved using a modified Krasnoselskij iteration process, which is much simpler to use than the other iteration schemes that have been defined. 2008 Elsevier Inc.

In this work, we present a two-dimensional mixed-hybrid finite element model of variably saturated flow on unstructured triangular meshes. Velocities are approximated using lowest order Raviart-Thomas (RT0) elements with piecewise constant pressure. The resulting nonlinear systems of algebraic equations are solved using Picard or Newton iterations in combination with ad hoc preconditioning tech...

Abstract This paper develops an efficient and robust solution technique for the steady Boussinesq model of non-isothermal flow using Anderson acceleration applied to a Picard iteration. After analyzing fixed point operator associated with nonlinear iteration prove that certain stability regularity properties hold, we apply authors’ recently constructed theory acceleration, which yields converge...

A multilevel wavelet algorithm is developed to solve integral equations for the pair correlations in simple liquids. The algorithm is based on the discrete wavelet transform of the radial correlation functions. The fundamental properties of wavelet bases are employed to improve the convergence and speed of the algorithm. The Coifman 2 basis set is used for the wavelet treatment. To solve the Or...

for all x, y ∈ C. We use F T to denote the set of fixed points of T , that is, F T {x ∈ C : Tx x}. Throughout the paper, we assume that F T / ∅. Construction of fixed points of nonlinear mappings is an important and active research area. In particular, iterative methods for finding fixed points of nonexpansive mappings have received a vast investigation; see 1–28 . It is well known that the Pic...
