Rational Points of Rationally Simply Connected Varieties
These are notes prepared for a series of lectures at the conference Variétés rationnellement connexes: aspects géométriques et arithmétiques of the Société Mathématique de France held in Strasbourg, France in May 2008.
متن کاملOn Unramified Morphisms of Affine Varieties into Simply Connected Non-singular Affine Varieties
The Jacobian Conjecture is the following : If φ ∈ Endk(Ank ) with a field k of characteristic zero is unramified, then φ is an automorphism. In this paper, This conjecture is proved affirmatively in the abstract way instead of treating variables in a polynomial ring. Let k be an algebraically closed field, let Ak = Max(k[X1, . . . , Xn]) be an affine space of dimension n over k and let f : Ak −...
متن کاملUnramified Cohomology of Classifying Varieties for Exceptional Simply Connected Groups
Let BG be a classifying variety for an exceptional simple algebraic group G. We compute the degree 3 unramified Galois cohomology of BG with values in (Q/Z)′(2) over a nearly arbitrary field F . Combined with a paper by Merkurjev, this completes the computation of these cohomology groups for G semisimple simply connected over (nearly) all fields. Let G be an algebraic group over a field F with ...
متن کاملOn Simply-connected 4-manifolds
This paper concerns (but does not succeed in performing) the diffeomorphism classification of closed, oriented, differential, simply-connected 4-manifolds. It arises out of the observation (due to Pontrjagin and Milnor [2]) that if two such manifolds Mx and M2 have isomorphic quadratic forms of intersection numbers on #2(Jft-), then there is a map / : M1-^-Mi which is a homotopy equivalence and...
متن کاملOn Non-formal Simply Connected Manifolds
We construct examples of non-formal simply connected and compact oriented manifolds of any dimension bigger or equal to 7.
