Ga-actions of fiber type on affine T-varieties
Alvaro Liendo
Let X be a normal affine T-variety, where T stands for the algebraic torus. We classify Ga-actions on X arising from homogeneous locally nilpotent derivations of fiber type. We ded…
Rational singularities of normal T-varieties
Alvaro Liendo
A T-variety is an algebraic variety X with an effective regular action of an algebraic torus T. Altmann and Hausen gave a combinatorial description of an affine T-variety X by mean…
Ranks of tensors and a generalization of secant varieties
Jarosław Buczyński, J. M. Landsberg
We introduce subspace rank as a tool for studying ranks of tensors and X-rank more generally. We derive a new upper bound for the rank of a tensor and determine the ranks of partia…
LG/CY correspondence: the state space isomorphism
Alessandro Chiodo, Yongbin Ruan
We prove the classical mirror symmetry conjecture for the mirror pairs constructed by Berglund, Hübsch, and Krawitz. Our main tool is a cohomological LG/CY correspondence which pro…
Remarques sur la cohomologie des groupes kählériens nilpotents
Benoît Claudon
In this note, we show that the cohomology groups of (virtually) nilpotent Kähler groups are naturally endowed with a mixed Hodge structure. These structures make the Hopf morphisms…
The canonical strip phenomenon for complete intersections in homogeneous spaces
Laurent Manivel
We show that a refined version of Golyshev's canonical strip hypothesis does hold for the Hilbert polynomials of complete intersections in rational homogeneous spaces.
