Stabilization of the Witt group
Max Karoubi
Using an idea due to R.Thomason, we define a "homology theory" on the category of rings which satisfies excision, exactness, homotopy (in the algebraic sense) and periodicity of or…
Complexe canonique d'une algèbre de Lie réductive
Jean-Yves Charbonnel
Let ${\goth g}$ be a finite dimensional complex reductive Lie algebra and $\dv ..$ an invariant non degenerated bilinear form on ${\goth g}\times {\goth g}$ which extends the Killi…
Complexe canonique de deuxième espèce, variété commutante et bicône nilpotent d'une algèbre de Lie réductive
Jean-Yves Charbonnel
Let be a finite dimensional complex reductive Lie algebra and <.,.> an invariant non degenerated bilinear form on which extends the Killing form of . We defi…
Endomorphisms of Deligne-Lusztig varieties
François Digne, Jean Michel
This paper is a following to math.RT/0410454. For a finite group of Lie type we study the endomorphisms, commuting with the group action, of a Deligne-Lusztig variety associated to…
On the global wellposedness of the 3-D Navier-Stokes equations with large initial data
Jean-Yves Chemin, Isabelle Gallagher
We give a condition for the periodic, three dimensional, incompressible Navier-Stokes equations to be globally wellposed. This condition is not a smallness condition on the initial…
Eigenvalues of Products of Unitary Matrices and Lagrangian Involutions
Elisha Falbel, Richard A. Wentworth
This paper introduces a submanifold of the moduli space of unitary representations of the fundamental group of a punctured sphere with fixed local monodromy. The submanifold is def…
