Normal affine surfaces with -actions
Hubert Flenner, Mikhail Zaidenberg
A classification of normal affine surfaces admitting a -action was given in the work of Białynicki-Birula, Fieseler and L. Kaup, Orlik and Wagreich, Rynes and others. We p…
Witten's top Chern class via K-theory
Alessandro Chiodo
The Witten top Chern class is the crucial cohomology class needed to state a conjecture by Witten relating the Gelfand-Dikii hierarchies to higher spin curves. In math.AG/0011032,…
Stable reductive varieties II: Projective case
Valery Alexeev, Michel Brion
We construct a moduli space of stable projective pairs with a nontrivial action of a connected reductive group. These stable reductive pairs are higher-dimensional analogs of stabl…
Stable reductive varieties I: Affine varieties
Valery Alexeev, Michel Brion
The motivation of this work is to construct an analog of compactified moduli of abelian varieties and toric pairs in the case of non-commutative algebraic group G. We introduce a c…
