COMPUTATIONAL METHODS IN ALGEBRA AND ANALYSIS

F. J. Castro-Jiménez

Resumen


This paper describes some applications of Computer Algebra to Algebraic Analysis also known as D-module theory, i.e. the algebraic study of the systems of linear partial differential equations. Gröbner bases for rings of linear differential operators are the main tools in the field. We start by giving a short review of the problem of solving systems of polynomial equations by symbolic methods. These problems motivate some of the later developed subjects.

Key words: Polynomial ring, polynomial system, ring of linear differential operators, differential system, D-module, Gröbner basis, division theorem, characteristic variety, irregularity, Bernstein-Sato polynomial, logarithmic Dmodule, projective module, syzygy, free resolution.
