Exposé on a conjecture of Tougeron

Joseph Becker (1977)

Annales de l'institut Fourier

An algebra homomorphism of the locatized affine rings of an algebraic variety is continuous in the Krull topology of the respective local rings. It is not necessarily open or closed in the Krull topology. However, we show that the induced map on the associated analytic local rings is also open and closed in the Krull topology. To do this we prove a conjecture of Tougeron which states that if η is an analytic curve on an analytic variety V and f is a formal power series which is convergent when restricted...

Inégalités de Łojasiewicz globales

Jean-Claude Tougeron (1991)

Annales de l'institut Fourier

On étudie les propriétés métriques des ensembles analytique réels f = 0 , avec f 𝒪 ( Ω ) , 𝒪 ( Ω ) algèbre analytique topologiquement noethérienne. Ainsi, on construit de larges classes d’algèbres 𝒪 ( Ω ) topologiquement noethériennes et vérifiant des conditions de Łojasiewicz globales d’un certain type. Comme application, on obtient des théorèmes de division de fonction 𝒞 par des fonctions analytiques.
