Modular Las Vegas Algorithms for Polynomial Absolute Factorization
Cristina Bertone, Guillaume Chèze, André Galligo
Let $f(X,Y) \in \ZZ[X,Y]$ be an irreducible polynomial over $\QQ$. We give a Las Vegas absolute irreducibility test based on a property of the Newton polytope of , or more preci…

A Borel open cover of the Hilbert scheme
Cristina Bertone, Paolo Lella, Margherita Roggero
Let be an admissible Hilbert polynomial in $\PP^n$ of degree . The Hilbert scheme $\hilb^n_p(t)$ can be realized as a closed subscheme of a suitable Grassmannian $ \mathb…
