Abstract: 

In this paper, rst the Newton's divided di erence interpolation method based on the gH di erence on Fuzzy data is introduced. Then the numerical methods entitled Fuzzy Euler and modi ed Fuzzy Euler are used to solve Fuzzy impulsive initial value problem. Moreover the algorithms for the Fuzzy impulsive initial value problem are explained and their local truncation errors are obtained in details. Finally, for more illustration some numerical examples are solved.

Abstract: 

We are concerned with the development of a k-step method for the numerical solution of Fuzzy initial value problems. Convergence and stability of the method are also proved in detail. Moreover, a specific method of order 4 is found. The numerical results show that the proposed fourth order method is efficient for solving Fuzzy differential equations.

Abstract: 

This paper presents the development and implementation of a numerical method forthe solution of one dimensional Mixed Fredholm Volterra Intergro-Differential Equations(MFVIDEs). The new technique transformed MFVIDEs into an integral equation whichis then approximated using a polynomial collocation method. Standard collocation pointsare then used to convert the problem into a system of algebraic equations. Some numericalexamples are used to test the efficiency and accuracy of the method. The results showthat the new method is efficient, accurate and easy to implement.

Abstract: 

IN THIS PAPER, WE INVESTIGATE THE EXISTENCE AND MULTIPLICITY OF POSITIVE SOLUTIONS FOR THE NONLINEAR FRACTIONAL DIFFERENTIAL EQUATION BOUNDARY value problem (FORMOLA) WHERE 0 < B < A < 1, DA0+ IS THE STANDARD RIEMANN-LIOUVILLE DIFFERENTIATION AND ¦: [0, 1] ´ [0,¥) ® [0,¥) IS CONTINUOUS. BY USING SOME FIXED-POINT RESULTS ON CONES, SOME EXISTENCE AND MULTIPLICITY RESULTS OF POSITIVE SOLUTIONS ARE OBTAINED.

Abstract: 

In this work, the Homotopy Perturbation Method (HPM) is implemented for finding approximate solution of the Fuzzy initial value problem (FIVP) involving generalized differentiability.This method is based upon homotopy perturbation theory. The comparison of the exact solution with approximate solution obtained by HPM is in detail. The results reveal that the method is very effective and simple.

Abstract: 

LET US CONSIDER THE initial-value problem FOR THE NONLINEAR SCHRODINGER EQUATION (FORMOLA) WHERE D = ¶2X1 + ... + ¶2XD IS THE LAPLACIAN IN D DIMENSIONS, V (X): RD ® R IS A BOUNDED POTENTIAL, AND ¦(|U|2): R+ ® R IS A REAL ANALYTIC FUNCTION. THE MAIN QUESTION IS: IF U0 Î HS(RD) FOR SOME S ³ 0, DOES THERE EXIST A UNIQUE LOCAL SOLUTION U(T) TO THE initial-value problem (1), WHICH REMAINS IN HS(RD) FOR ALL T Î [0,T] AND, IF IT IS SO, DOES IT EXTEND GLOBALLY FOR ALL TIMES T Î R+? THE CLASSICAL THEORY OF PARTIAL DIFFERENTIAL EQUATIONS CONSIDERS SMOOTH SOLUTIONS FOR LARGE valueS OF S ³ 0. IT WAS ONLY RECENTLY THIS THEORY WAS EXTENDED TO SOLUTIONS OF LOW REGULARITY (FOR SMALLER valueS OF S). THE FOLLOWING THEOREM GIVES LOCAL WELL-POSEDNESS OF initial-value problem (1) IN HS(RD) FOR S > D/2 .
