A Refinement of a Mixed Sparse Effective Nullstellensatz
Jan Tuitman · International Mathematics Research Notices · 2010
For k ≥ n + 1 Laurent polynomials f1, …, fk in n variables which are allowed to have different Newton polytopes, we give a generically satisfied criterion under which we can find Laurent polynomials h1, …, hk, with particularly small Newton polytopes, such that . This gives a refinement of a result of Canny and Emiris.
