Numerical Solution of Mixed Volterra – Fredholm Integral Equation Using the Collocation Method
مجلة بغداد للعلوم, 2020 Volterra – Fredholm integral equations (VFIEs) have a massive interest from researchers recently. The current study suggests a collocation method for the mixed Volterra - Fredholm integral equations (MVFIEs)."A point interpolation collocation method is ...

Boundary element collocation methods using splines with multiple knots [PDF]
, 1995 We extend the theory of boundary element collocation methods by allowing reduced inter-element smoothness (or in other words, by allowing trial functions that are splines with multiple knots).

The residual and the error for collocation methods
International Journal of Mathematics and Mathematical Sciences, 2001 We use earlier results on collocation matrices related to the solution and its derivatives in describing asymptotic relation between the error on the highest derivative and the residuals. That justifies the use of the form of the residual rather than its

New recursive approximations for variable-order fractional operators with applications
Mathematical Modelling and Analysis, 2018 To broaden the range of applicability of variable-order fractional differential models, reliable numerical approaches are needed to solve the model equation.In this paper, we develop Laguerre spectral collocation methods for solving variable-order ...

Multi-Index Stochastic Collocation for random PDEs [PDF]
, 2016 In this work we introduce the Multi-Index Stochastic Collocation method (MISC) for computing statistics of the solution of a PDE with random data. MISC is a combination technique based on mixed differences of spatial approximations and quadratures over ...

Advanced Science, EarlyView.Non‐volatile voltage control of magnetic configurations is achieved in a strain‐coupled multiferroic heterostructure. Voltage pulses reversibly interconvert giant single‐domain and multidomain magnetic states, which remain stable at zero applied voltage. ABSTRACT Voltage control of magnetic states in multiferroic heterostructures represents a promising

A Local Strong form Meshless Method for Solving 2D time-Dependent Schrödinger Equations
پژوهشهای ریاضی, 2018 This paper deals with the numerical solutions of the 2D time dependent Schr¨odinger equations by using a local strong form meshless method. The time variable is discretized by a finite difference scheme. Then, in the resultant elliptic type PDEs, special
