About the Trimmed and the Poincare-Dulac normal form of diffeomorphisms

Three necessary conditions are immediately pointed out by Strong to make a successful stabilization: (i) the Bank de France must be independent from government and fiscal policy;

Ainsi, l’espace G des couples de points distincts du bord peut ˆetre identifi´e `a l’espace des g´eod´esiques orient´ees du disque et la th´eorie g´en´erale des

This is done just as in Theorem 3.3 for divisorial valuations since there are no strict transforms of the branches gC i at points of the exceptional divisor with G x =G (and thus

Cette estimation et sa preuve ont cependant deux d´ efauts : c’est une preuve “tr` es lin´ eaire” (elle ne s’adapte pas ` a un cadre plus g´ en´ eral d’´ equations

These results are deduced from several functional inequalities, among them the Nash inequality, the Poincar´ e inequality and the Log-Sobolev inequality.. Let us emphasize that the

The proof is “completely linear” (in the sense that it can not be generalized to a nonlinear equation) and the considered initial data are very confined/localized (in the sense

Although the Hardy inequality corresponding to one quadratic singularity, with optimal constant, does not admit any extremal function, it is well known that such a potential can
