Convergence analysis of general spectral methods
If a spectral numerical method for solving ordinary or partial differential equations is written as a biinfinite linear system b = Za with a map Z : l2 → l2 that has a continuous inverse, this paper shows that one can discretize the biinfinite system in such a way that the resulting finite linear system b̃ = Z̃ã is uniquely solvable and is unconditionally stable, i.e. the stability can be made to...
متن کاملHigh-Order Convergence of Spectral Deferred Correction Methods on General Quadrature Nodes
It has been demonstrated that spectral deferred correction (SDC) methods can achieve arbitrary high order accuracy and possess good stability properties. There have been some recent interests in using high-order Runge-Kutta methods in the prediction and correction steps in the SDC methods, and higher order rate of convergence is obtained provided that the quadrature nodes are uniform. The assum...
متن کاملConvergence analysis of spectral Tau method for fractional Riccati differential equations
In this paper, a spectral Tau method for solving fractional Riccati differential equations is considered. This technique describes converting of a given fractional Riccati differential equation to a system of nonlinear algebraic equations by using some simple matrices. We use fractional derivatives in the Caputo form. Convergence analysis of the proposed method is given an...

Fuzzy integral equations have a major role in the mathematics and applications.In this paper, general fuzzy integral equations with nonlinear fuzzykernels are introduced. The existence and uniqueness of their solutions areapproved and an upper bound for them are determined. Finally an algorithmis drawn to show theorems better.
متن کاملRates of Convergence of Spectral Methods for Graphon Estimation
This paper studies the problem of estimating the grahpon model – the underlying generating mechanism of a network. Graphon estimation arises in many applications such as predicting missing links in networks and learning user preferences in recommender systems. The graphon model deals with a random graph of n vertices such that each pair of two vertices i and j are connected independently with p...
