【Abstract】 The theory about common factor of polynomials is very important in many research fields,such as symbolic computation,interpolation theory,automatic theorem proving,and robotics.This paper introduces the cofactor system of a polynomial system on unique factorization domain.Using the cofactor system,it obtains a criterion on common factor with given arbitrary degree.This result provides a theory foundation of application in computational algebraic geometry and other corresponding fields.更多还原
