On the third secant variety

Jarosław Buczyński, J. M. Landsberg

We determine normal forms and ranks of tensors of border rank at most three. We present a differential-geometric analysis of limits of secant planes in a more general context. In p…

Acyclic curves and group actions on affine toric surfaces

I. Arzhantsev, M. Zaidenberg

We show that every irreducible, simply connected curve on a toric affine surface X over the field of complex numbers is an orbit closure of a multiplicative group action on X. It f…

Triangulations and Severi varieties

Frédéric Chapoton, Laurent Manivel

We consider the problem of constructing triangulations of projective planes over Hurwitz algebras with minimal numbers of vertices. We observe that the numbers of faces of each dim…

Flexibility of affine cones over del Pezzo surfaces of degree 4 and 5

Alexander Perepechko

We prove that the action of the special automorphism group on affine cones over del Pezzo surfaces of degree 4 and 5 is infinitely transitive.

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…

Abelian varieties and theta functions associated to compact Riemannian manifolds; constructions inspired by superstring theory

Stefan Müller-Stach, Chris Peters, Vasudevan Srinivas

We look into a construction of principal abelian varieties attached to certain spin manifolds, due to Witten and Moore-Witten around 2000 and try to place it in a broader framework…
