Scrolls and hyperbolicity
Ciro Ciliberto, Mikhail Zaidenberg
Using degeneration to scrolls, we give an easy proof of non-existence of curves of low genera on general surfaces in P3 of degree d >=5. We show, along the same lines, boundedness…
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…
Equivariant Chow ring and Chern classes of wonderful symmetric varieties of minimal rank
Michel Brion, Roy Joshua
We describe the equivariant Chow ring of the wonderful compactification of a symmetric space of minimal rank, via restriction to the associated toric variety . Also, we show…
3-fold symmetric products of curves as hyperbolic hypersurfaces in $\Proj^4$
Ciro Ciliberto, Mikhail Zaidenberg
We construct new examples of Kobayashi hyperbolic hypersurfaces in the projective 4-space. They are generic projections of the triple symmetric product of a generic curve of genus…
