Polynomial and rational solutions of holonomic systems
The aim of this paper is to give two new algorithms, which are elimination
free, to find polynomial and rational solutions for a given holonomic system
associated to a set of linear differential operators in the Weyl algebra D =
k where k is a subfield of the complex numbers.Comment: 20 page
Algebraic computation of some intersection D-modules
Let be a complex analytic manifold, a locally
quasi-homogeneous free divisor, an integrable logarithmic connection with
respect to and the local system of the horizontal sections of on
. In this paper we give an algebraic description in terms of of the
regular holonomic D-module whose de Rham complex is the intersection complex
associated with . As an application, we perform some effective computations
in the case of quasi-homogeneous plane curves.Comment: 18 page
On Computing Groebner Basis in the Rings of Differential Operators
Insa and Pauer presented a basic theory of Groebner basis for differential
operators with coefficients in a commutative ring in 1998, and a criterion was
proposed to determine if a set of differential operators is a Groebner basis.
In this paper, we will give a new criterion such that Insa and Pauer's
criterion could be concluded as a special case and one could compute the
Groebner basis more efficiently by this new criterion
