Locally unsplit families of rational curves of large anticanonical degree on Fano manifolds

Cinzia Casagrande, Stéphane Druel

In this paper we address Fano manifolds X with a locally unsplit dominating family of rational curves of anticanonical degree equal to the dimension of X. We first observe that the…

Ga-actions on affine cones

Takashi Kishimoto, Yuri Prokhorov, Mikhail Zaidenberg

We give a criterion of existence of a unipotent group action on the affine cone over a projective variety or, more generally, on the affine quasicone over a variety which is projec…

The space of generalised G2-theta functions of level one

Chloé Grégoire, Christian Pauly

Let C be a smooth projective complex curve of genus at least 2. For a simply-connected complex Lie group G the vector space of global sections H^0(M(G), L^l) of the l-th power of t…

Schémas de Hilbert invariants et théorie classique des invariants

Ronan Terpereau

Let W be an affine variety equipped with an action of a reductive group G. The invariant Hilbert scheme is a moduli space which classifies the G-stable closed subschemes of W such…

Les groupes de Burger-Mozes ne sont pas kählériens

Thibaut Delcroix

Burger and Mozes constructed examples of infinite simple groups which are lattices in the group of automorphisms of a cubical building. We show that there can be no morphism with f…

Deformation of Kähler manifolds

Junyan Cao

It has been shown by Claire Voisin in 2003 that one cannot always deform a compact Kähler manifold into a projective algebraic manifold, thereby answering negatively a question rai…
