On the period map for prime Fano threefolds of degree 10
O. Debarre, A. Iliev, L. Manivel
We prove that the deformations of a smooth complex Fano threefold X with Picard number 1, index 1, and degree 10, are unobstructed. The differential of the period map has two-dimen…
Lowest Weights in Cohomology of Variations of Hodge Structure (II)
Chris Peters, Morihiko Saito
Let be an irreducible complex analytic space with $j:U\into X$ an immersion of a smooth Zariski open subset, and let $\bV$ be a variation of Hodge structure of weight over…
Landau-Ginzburg/Calabi-Yau correspondence for quintic three-folds via symplectic transformations
Alessandro Chiodo, Yongbin Ruan
We compute the recently introduced Fan-Jarvis-Ruan-Witten theory of W-curves in genus zero for quintic polynomials in five variables and we show that it matches the Gromov-Witten g…
Affine T-varieties of complexity one and locally nilpotent derivations
Alvaro Liendo
Let X=spec A be a normal affine variety over an algebraically closed field k of characteristic 0 endowed with an effective action of a torus T of dimension n. Let also D be a homog…
Smooth Affine Surfaces with Non-Unique C*-Actions
Hubert Flenner, Shulim Kaliman, Mikhail Zaidenberg
In this paper we complete the classification of effective C*-actions on smooth affine surfaces up to conjugation in the full automorphism group and up to inversion of C*. If a smoo…
Embeddings of C*-surfaces into weighted projective spaces
Hubert Flenner, Shulim Kaliman, Mikhail Zaidenberg
Let V be a normal affine surface which admits a C*- and a C+-action. In this note we show that in many cases V can be embedded as a principal Zariski open subset into a hypersurfac…
