摘要
For k >= n + 1 Laurent polynomials f(1),..., f(k) in n variables which are allowed to have different Newton polytopes, we give a generically satisfied criterion under which we can find Laurent polynomials h(1),..., h(k), with particularly small Newton polytopes, such that h(1)f(1) + ... + h(k)f(k) = 1. This gives a refinement of a result of Canny and Emiris.
