SUMMARY:Ensembles sous-analytiques surconvergents dans les espaces de Berkovich
DESCRIPTION:Si X est un espace k-affinoïde (k étant un corps non-archimédien)\, un sous-ensemble S de X est dit sous-analytique surconvergent si on peut ?Roeessentiellement?R l’écrire S=f(Y) où f est un morphisme surconvergent d’espaces affinoïdes.Nous expliquerons d’abord comment décrire ces ensembles en n’utilisant que des fonctions de X\, i.e. sans avoir recours à une projection. Il s’agit d’une version géométrique d’un résultat de H. Schoutens qui utilise l’élimination des quantificateurs dans ACVF.Nous montrerons ensuite que les ensembles sous-analytiques surconvergents peuvent être définis localement pour la topologie de Berkovich\, mais pas pour la G-topologie.

SUMMARY:Sheaves on subanalytic sites
DESCRIPTION:Sheaf theory is not well suited to study objects which are not defined by local properties. It is the case\, for example\, of functional spaces with growth conditions\, as tempered distributions. Since the study of the solutions of a system of PDE in these spaces is of great importance (solutions of irregular D-modules\, Laplace transform\, etc.)\, many ways have been explored by the specialists to overcome this problem. For this purpose Kashiwara and Schapira introduced the subanalytic site and proved that some of these spaces can be realized as sheaves on a subanalytic site. In this talk we will recall the theory of subanalytic sheaves and give an overview of some recent developments and applications.

SUMMARY:Imaginaries in valued fields
DESCRIPTION:It is now well-known what sorts have to be added to a valued field in order to achieve elimination of imaginaries. It is also known that these sorts do not suffice to eliminate imaginaries when the field is enhanced by restricted analytic functions\, despite the fact that the theories still have quantifier elimination. In this talk\, I will attempt to convey the intuition about the definable sets in a valued field that underlies all of these results (while explaining the model-theoretic terminology in the above).
