OVERVIEW

Two years ago, we ran a thematic program on o-minimality and real analytic geometry. Its main focus was on extending local resolution of singularities techniques in order to establish the o-minimality of certain expansions of the real field, such as those generated by the functions studied by Ilyashenko and Ecalle in his proof of Dulac’s problem. Many recent developments in the intersection of o-minimality and real analytic geometry use resolution of singularities in crucial ways, and they can in turn be viewed as extending the notion of resolution of singularities in the sense of the preparation theorems mentioned above. There is good reason to believe that extending resolution algorithms to certain classes of functions involving exponential scales may help shed new light on various interesting problems in real analytic geometry, coming from Pfaffian geometry and dynamical systems. Examples of particular interest to us are the classes of multisummable and of resurgent functions. This workshop will survey progress made during and after our programme, with a particular emphasis on work done by the (then) more junior participants.
