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…
Conchoidal transform of two plane curves
Alberto Albano, Margherita Roggero
The conchoid of a plane curve is constructed using a fixed circle in the affine plane. We generalize the classical definition so that we obtain a conchoid from any pair of…
Rational components of Hilbert schemes
Paolo Lella, Margherita Roggero
The Gröbner stratum of a monomial ideal $\id{j}$ is an affine variety that parametrizes the family of all ideals having $\id{j}$ as initial ideal (with respect to a fixed term orde…
Homogeneous varieties for Hilbert schemes
Giorgio Ferrarese, Margherita Roggero
The paper concerns the affine varieties that are homogeneous with respect to a (non-standard) graduation over the group Z^m. Among the other properties it is shown that every such…
