Title: Expansions of the real that do not define new smooth functions
Speaker: Alex Savatovsky (University of Konstanz)
Abstract: We will give some conditions under which an expansion of the real field does not define any new (that is, not semialgebraic) infinitely differentiable functions. We will give a very rough sketch of the proof and discuss generalizations.
