Additive and Multiplicative Coinvariant Spaces of Weyl Groups in the Light of Harmonics and Graded Transfer
Sebastian Debus, Tobias Metzlaff
The action of a Weyl group on the associated weight lattice induces an additive action on the symmetric algebra and a multiplicative action on the group algebra of the lattice. We…
Collineation varieties of tensors
Fulvio Gesmundo, Hanieh Keneshlou
In this article, we introduce the -th collineation variety of a third order tensor. This is the closure of the image of the rational map of size minors of a matrix of linear…
Extensions of curves with high degree with respect to the genus
Ciro Ciliberto, Thomas Dedieu
We classify linearly normal surfaces of degree such that , where is the sectional genus (it is a classical result that…
Partial Degeneration of Tensors
Matthias Christandl, Fulvio Gesmundo, Vladimir Lysikov +1
Tensors are often studied by introducing preorders such as restriction and degeneration: the former describes transformations of the tensors by local linear maps on its tensor fact…
A Viro-Zvonilov-type inequality for Q-flexible curves of odd degree
Anthony Saint-Criq
We define an analogue of the Arnold surface for odd degree flexible curves, and we use it to double branch cover -flexible embeddings, where -flexible is a condition to be ad…
Nonemptiness of Severi varieties on Enriques surfaces
Ciro Ciliberto, Thomas Dedieu, Concettina Galati +1
Let be a general polarized Enriques surface, with not numerically 2-divisible. We prove the existence of regular components of all Severi varieties of irreducible -n…
