Gröbner bases and critical values: The asymptotic combinatorics of determinantal systems

Alin Bostan, Jérémy Berthomieu, Andrew Ferguson +1

We consider ideals involving the maximal minors of a polynomial matrix. For example, those arising in the computation of the critical values of a polynomial restricted to a variety…

On the computation of asymptotic critical values of polynomial maps and applications

Jérémy Berthomieu, Andrew Ferguson, Mohab Safey El Din

Let $f = (f_{1}, \dots, f_{p})$ be a polynomial tuple in $Q [z_{1}, \dots, z_{n}]$ and let $d = max_{1 \leq i \leq p} ° f_{i}$ . We consider the problem of comput…
