Outline of Final Research Achievements

We studied and introduced new formula for hypergeometric functions by using technique of computer algebra. Rational Transformation for hypergeometric functions, development of new method for exactly computing special values of A-hypergeometric polynomials without Groebner theory, an algorithm for computing b-functions on parametric D-modules, Grothendieck local residues in special case. We implemented our algorithms on Risa/Asir a computer algebra system.
