Differential Galois Theory and Hopf Algebras for Lie Pseudogroups

open access: yesAxioms
According to a clever but rarely quoted or acknowledged work of E. Vessiot that won the prize of the Académie des Sciences in 1904, “Differential Galois Theory” (DGT) has mainly to do with the study of “Principal Homogeneous Spaces” (PHSs) for finite ...

Extending divisors from complete intersection surfaces

open access: yesLe Matematiche, 2007
The aim of this paper is to extend a theorem of Griffiths, Harris and Hulek [4], [6] on the extendability of divisors of a smooth complete intersection surface in P^n to the case when the ambient space is a product of projective spaces or a Grassmannian.

On the v-Picard Group of Stein Spaces

open access: yesInternational Mathematics Research Notices
Abstract We study the image of the Hodge–Tate logarithm map (in any cohomological degree), defined by Heuer, in the case of smooth Stein varieties. Heuer, motivated by the computations for the affine space of any dimension, raised the question whether this image is always equal to the group of closed differential forms.

Picard Groups of Hypersurfaces In Toric Varieties

open access: yesPublications of the Research Institute for Mathematical Sciences, 1996
We study the structure of rational Picard groups of hypersurfaces of toric varieties. By using the fan structure associated to the ambient toric variety, an explicit basis of the Picard group is described by certain combinatorial data. We shall also discuss the application to Calabi-Yau spaces.

Local Picard Groups

open access: yes, 2011
We use our extension of the Noether-Lefschetz theorem to describe generators of the class groups at the local rings of singularities of very general hypersurfaces containing a fixed base locus. We give several applications, including (1) every subgroup of the class group of the completed local ring of a rational double point arises as the class group ...

Approaching Argyres-Douglas theories

open access: yesJournal of High Energy Physics
The Seiberg-Witten solution to four-dimensional N $$ \mathcal{N} $$ = 2 super-Yang-Mills theory with gauge group SU(N) and without hypermultiplets is used to investigate the neighborhood of the maximal Argyres-Douglas points of type a 1 a N − 1 $$ \left({
