THE RATIONAL STABLE HOMOLOGY OF MAPPING CLASS GROUPS OF UNIVERSAL NIL-MANIFOLDS

This is made by using general properties of Segal’s machinery [14] associating a spectrum to each symmetric monoidal category, and Galatius theorem [7] showing that the

We use a lemma (furuncle-lemma) of Andreotti- Grauert and a theorem of Coen which extends the results of Sorani to the case of an open subset of a Stein

Birational automorphism groups and the movable cone theorem for Calabi- Yau manifolds of Wehler type via universal Coxeter groups.1. TYPE VIA UNIVERSAL

It will follow that X(fe)/B is finite for any smooth rational surface over a global field, and that all points are Brauer equivalent at good reduction places.. This explains

We use the relations between the braid and mapping class groups of a compact, connected, non-orientable surface N without boundary and those of its orientable double covering S to

The basis we propose avoids this diiHculty, as it consists of cycles whose generic points correspond to reduced length d subschemes of P2.. We obtain a geometric

be proved by the methods of [3]. There we proved only the topological equivalence of the action to the orthogonal one given by r, and left the remainder of the proof
