Multivariate GCDs over Algebraic Function FieldsMichael Monagan, CECMFriday January 27th, 2006, in K9509 at 10:30am.
Abstract: We have implemented the multivariate modular gcd routine of Monagan and van Hoeij (2004) for polynomials over algebraic function fields. In this presentation we outline the main steps of the algorithm and present some timings for dense and sparse gcd problems comparing our algorithm to Maple's built-in subresultant implementation. |
