An algorithm for the normal bundle of rational monomial curves

Alberto Alzati, Riccardo Re, Alfonso Tortora

We give an algorithm for calculating the splitting type of the normal bundle of any rational monomial curve. The algorithm is obtained by reducing the calculus to a combinatorial p…

Monomial invariants in codimension two

A. Alzati, A. Tortora

We define the monomial invariants of a projective variety $Z$ ; they are invariants coming from the generic initial ideal of $Z$ . Using this notion, we generalize a result of Cook:…

Hodge-Gaussian maps

Elisabetta Colombo, Gian Pietro Pirola, Alfonso Tortora

Let $X$ be a compact Kähler manifold, and let $L$ be a line bundle on $X .$ Define $I_{k} (L)$ to be the kernel of the multiplication map $S y m^{k} H^{0} (L) \to H^{0} (L^{k}) .$ For all $h \le…
