Twisted Gromov-Witten r-spin potential and Givental's quantization
Alessandro Chiodo, Dimitri Zvonkine
The universal curve p:C->\Mbar over the moduli space \Mbar of stable r-spin maps to a target Kähler manifold X carries a universal spinor bundle L->C. Therefore the moduli space \M…
Quantum cohomology of minuscule homogeneous spaces III : semi-simplicity and consequences
Pierre-Emmanuel Chaput, Laurent Manivel, Nicolas Perrin
We prove that the quantum cohomology ring of any minuscule or cominuscule homogeneous space, specialized at q=1, is semisimple. This implies that complex conjugation defines an alg…
Anti-affine algebraic groups
Michel Brion
We say that an algebraic group over a field is anti-affine if every regular function on is constant. We obtain a classification of these groups, with applications to the st…
Autour de la cohomologie de Bott-Chern
Michel Schweitzer
The goal of the memoir is to develop a new cohomology theory which encompasses De Rham and Dolbeault cohomology as well as Deligne Beilinson cohomology, in the context of general c…
Uniqueness of - and -actions on Gizatullin surfaces
Hubert Flenner, Shulim Kaliman, Mikhail Zaidenberg
A Gizatullin surface is a normal affine surface over , which can be completed by a zigzag; that is, by a linear chain of smooth rational curves. In this paper we deal wi…
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…
