Abstract

This paper deals with the solution of boundary value problems for ordinary differential equations with general boundary conditions. We obtain closed-form solutions in a symbolic form of problems with the general n-th order differential operator, as well as the composition of linear operators. The method is based on the theory of the extensions of linear operators in Banach spaces.

Highlights

  • Differential equations model numerous phenomena and processes in sciences and engineering

  • Boundary value problems for elementary differential equations with classical boundary conditions have been studied exhaustively by many researchers and comprehensive material is included in various standard texts

  • Ordinary differential equations with non-local boundary conditions were first studied at the beginning of the 20th century in [2,3,4], and later in [5]

Summary

Introduction

Differential equations model numerous phenomena and processes in sciences and engineering. Ordinary differential equations with non-local boundary conditions were first studied at the beginning of the 20th century in [2,3,4], and later in [5]. A description of the theory and the different directions of differential equations with non-local boundary conditions are given in the monograph [12]. Boundary value problems with multipoint and integral conditions have been studied in [26,27,28,29,30,31,32], and others. The present paper aims at providing a framework for symbolic computations for the solution of linear ordinary differential equations of order n with the most general multipoint and integral conditions, and boundary value problems for powers and products of differential operators.
