We prove that a metric space is an ANR if, and only if, every open subset of X has the homotopy type of a CW-complex.

We give the Thom polynomials for the singularities associated with maps with parameter . Our computations combine the characterization of Thom polynomials via the “method of restriction equations” of Rimanyi et al. with the techniques of Schur functions.

Nous généralisons le théorème de Cobham ([2]), en démontrant qu'une partie infinie de ℕ est reconnaissable en base k (k entier strictement plus grand que un) et reconnaissable dans un système de numération associé à un nombre de Pisot unitaire (ayant une propriété arithmétique supplémentaire) si et seulement si elle est ultimement périodique.

For A ⊂ I = [0,1], let be the set of continuous real-valued functions on I which vanish on a neighborhood of A. We prove that if A is an analytic subset which is not an and whose closure has an empty interior, then is homeomorphic to the space of differentiable functions from I into ℝ.
