The collection of semi-algebraic sets enjoys stability by many natural operation (taking the topological closure, projecting,...) making it a rich tool to use,</span><span style="text-align: justify; -webkit-text-stroke-color: rgb(0, 0, 0); -webkit-text-stroke-width: initial;"> </span><span style="text-align: justify; -webkit-text-stroke-color: rgb(0, 0, 0); -webkit-text-stroke-width: initial;">and at the same time its objects satisfy geometric theorems (stratification in smooth manifolds,...) that allow to keep control on their behaviour.</span></font></p>

<p style="font-weight: normal;"><font face="times new roman, new york, times, serif"><span style="-webkit-text-stroke-color: rgb(0, 0, 0); -webkit-text-stroke-width: initial;">O-minimality is an axiomatic approach which capture many of these features of semi -algebraic geometry. This axiomatic generalisation is successful in at least two sense: it preserves most of the nice properties of semi-algebraic geometry, and at the same time it has many natural witnesses that allow to "export" these properties outside of the algebraic world. I will give an overview of results concerning these two aspect of o-minimality.</span><span style="text-align: justify; -webkit-text-stroke-color: rgb(0, 0, 0); -webkit-text-stroke-width: initial;"> </span><span style="text-align: justify; -webkit-text-stroke-color: rgb(0, 0, 0); -webkit-text-stroke-width: initial;"> </span></font></p>
