Title: Approximating suprema of integrated subanalytic functions

Abstract: The class of constructible functions is by definition the closure of the class of restricted (globally) subanalytic functions under parametric integration. In some sense, they are for the real numbers what motivic functions are for p-adic fields. Somewhat surprisingly, some developments for real constructible functions lag behind results on the valued fields side. Notably, there is the question of whether the parametric supremum of constructible functions can be well-approximated by functions of the same class.
