On the degrees of bases of free modules over a polynomial ring

Let k be an infinite field, A the polynomial ring k[x1 , . . . , xn] and F ∈ AN×M a matrix such that Im F ⊂ AN A-free (in particular, Quillen-Suslin Theorem implies that Ker F is also free). Let D be the maximum of the degrees of the entries of F and s the rank of F. We show that there exists a basi...
