Fast evaluation of holonomic functions near and in regular singularities. (English) Zbl 0982.65024
The author obtains efficient algorithms for the evaluation of holonomic functions, which satisfy a linear differential equation $$Lf= 0$$, near and in singular points where the differential operator $$L$$ is regular or quasi-regular.
