Riemannian Geometries

In this paper we provide a non-commutative version of the fundamental class [dM ] = [(L 2(M,Λ∗(T ∗M)), d+ d∗, ε)] of a smooth closed Riemannian manifold M . The formulation involves elements of A. Connes’ non-commutative geometry, G. Kasparov’s KK-theory and the standard theory of von Neumann algebras. Using axioms based on [C1], it is proved we can recover the ordinary differential geometry of...

— In this Proceedings paper we describe a new notion of tame geometry by the author and F. Loeser, named b-minimality, put it in context, and compare it with other notions like o-minimality, C-minimality, p-minimality, and so on. Proofs are given elsewhere.

Reminiscences about numerical schemes

This preprint appeared firstly in Russian in 1997. Some truncated versions of this preprint were published in English and French, here a fully translated version is presented. The translation in English was done by O. V. Feodoritova and V. Deledicque to whom I express my gratitude. Key-words: Godunov’s Scheme, hyperbolic systems of conservation laws. ∗ Sobolev Institute of Mathematics, Novosibi...
