Let Ω be a bounded open subset of R n; with every measurable subset A of Ω is associated the real number En(A), related to capacity (for electrostatic problems) or to heat flux (for problems of thermal conduction). One investigates the minimization of En(A) when the measure of A is imposed. Penalty methods allows one to apply some techniques of convex analysis. 相似文献

Résumé Si Λ est la catégorie des espaces localement convexes séparés et complets, nous montrons que la catégorie duale de Λ est une
catégorie presque-abélienne et par suite, la catégorie Λ l’est aussi.

Résumé Cet article a bénéficié de nombreuses conversations avec G. Mokobodzki. Qu'il en soit ici remercié.
The purpose of this paper is to apply methods previously developed by the author for the optimal stopping problem to a zero sum game where both control variables are stopping times.相似文献

We continue the study of G. Castelnuovo on the group of birational transformations of the complex plane that fix each point
of a curve of genus > 1 ; we use adjoint linear system of the curve as Castelnuovo does. We prove that these groups are abelian,
and that these are either finite, of order 2 or 3, or conjuguate to a subgroup of the de Jonquières group. We show also that
these results do not generalise to curves of genus ≤ 1.

Résumé. We investigate and improve on a proof of Mertens concerning the distribution of primes in arithmetic progressions. As a by-product,
we establish fairly efficient numerical bounds for related quantities.

We introduce and study an interacting particle system. The evolution is Markovian. The elementary step of the dynamics is the following: one point is randomly chosen in the ambient space, the nearest particle moves to that point. We investigate in particular equilibrium properties of the system. To cite this article: J.-B. Gouéré, C. R. Acad. Sci. Paris, Ser. I 342 (2006). 相似文献

We prove a separation theorem for oriented matroids of rank 3. We give short combinatorial proofs of Carathéodory's theorem for arrangements of pseudohyperplanes and Kirchberger's theorem for arrangements of pseudolines. 相似文献

We give criteria for R-equivalence of torsors under finite constant group schemes over a field. In particular, using bitorsors, we obtain a Galois dévissage result which formalises and generalises a theorem of Philippe Gille in the case of local fields; for instance, Gille's theorem is shown to extend to higher local fields. 相似文献
