Method of Factorization of Ordinary Differential Operators and Some of Its Applications

نویسنده

  • Lev M. Berkovich
چکیده

The paper is dedicated to analytical and algebraic approaches to the problem of the integration of ordinary differential equations. The first part is devoted to linear ordinary differential equations of the second and nth orders, while the second deals with nonlinear ordinary differential equations. Factorization of nonlinear equations of the second and the third orders both through commutative and noncommutative nonlinear differential operators are considered. The method of the exact linearization for nonlinear equations is explained. Some applications are also considered.

F-TRANSFORM FOR NUMERICAL SOLUTION OF TWO-POINT BOUNDARY VALUE PROBLEM

We propose a fuzzy-based approach aiming at finding numerical solutions to some classical problems. We use the technique of F-transform to solve a second-order ordinary differential equation with boundary conditions. We reduce the problem to a system of linear equations and make experiments that demonstrate applicability of the proposed method. We estimate the order of accuracy of the proposed ...

New operators through measure of non-compactness

In this article, we use two concepts, measure of non-compactness and Meir-Keeler condensing operators. The measure of non-compactness has been applied for existence of solution nonlinear integral equations, ordinary differential equations and system of differential equations in the case of finite and infinite dimensions by some authors. Also Meir-Keeler condensing operators are shown in some pa...

Factorization in categories of systems of linear partial differential equations

where the coefficients fs(x) belong to some differential field K. Factorization is a useful tool for computing a closed form solution of the corresponding linear ordinary differential equation Ly = 0 as well as determining its Galois group (see for example [46, 47, 54]). For simplicity and without loss of generality we suppose that operators (1) are reduced (i.e. f0(x) ≡ 1) unless we explicitly...
