Affine cones over Fano threefolds and additive group actions
Takashi Kishimoto, Yuri Prokhorov, Mikhail Zaidenberg
We address the following question: When an affine cone over a smooth Fano threefold admits an effective action of the additive group? In this paper we deal with Fano threefolds of…
The space of generalized G2-theta functions
Chloé Grégoire
Let G2 be the exceptional Lie group of automorphisms of the complex Cayley algebra and C be a smooth, connected, projective curve of genus at least 2. Using the map obtained from e…
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…
Invariant Hilbert schemes
Michel Brion
This is a survey article on moduli of affine schemes equipped with an action of a reductive group. The emphasis is on examples and applications to the classification of spherical v…
