Outline of Final Research Achievements

We give numerical analysis algorithms and implementations for the following problems over the rational number fields, which give high precision numerical outputs. (1) fast evaluation method of iterations of linear transformations by a modular arithmetic and a distributed computation. (2) an efficient variation of the Bulirsch-Stoer method to solve linear ordinary differential equations numerically over rational numbers. An application of (1) is an exact evaluation of A-hypergeometric polynomial. An application of (2) is a numerical analysis near singular points of linear ordinary differential equations.
