Maximal disjoint Schubert cycles in rational homogeneous varieties
Roberto Muñoz, Gianluca Occhetta, Luis E. Solá Conde
In this paper we study properties of the Chow ring of rational homogeneous varieties of classical type, more concretely, effective zero divisors of low codimension, and a related i…
On the classification of non-big Ulrich vector bundles on fourfolds
Angelo Felice Lopez, Roberto Muñoz, José Carlos Sierra
We give an almost complete classification of non-big Ulrich vector bundles on fourfolds. This allows to classify them in the case of Picard rank one fourfolds, of Mukai fourfolds a…
Non-big Ulrich bundles: the classification on quadrics and the case of small numerical dimension
Angelo Felice Lopez, Roberto Muñoz, José Carlos Sierra
On any smooth -dimensional variety we give a pretty precise picture of rank Ulrich vector bundles with numerical dimension at most . Also, we classify non-b…
On the classification of non-big Ulrich vector bundles on surfaces and threefolds
Angelo Felice Lopez, Roberto Muñoz
We classify Ulrich vector bundles that are not big on smooth complex surfaces and threefolds.
Discriminants of Toric Varieties
Roberto Muñoz, Álvaro Nolla
We study the subvariety of singular sections, the discriminant, of a base point free linear system on a smooth toric variety . On one hand we describe pairs for wh…
Nestings of rational homogeneous varieties
Roberto Muñoz, Gianluca Occhetta, Luis E. Solá Conde
In this paper we study the existence of sections of universal bundles on rational homogeneous varieties -- called nestings -- classifying them completely in the case in which the L…
