Together with van der Hoeven they showed that the theory of pre-H-fields has a model companion that is almost the theory of transseries, in particular, the model companion is "exponentially bounded" in a way that can be made precise. I will discuss a theory of pre-H-fields having a model companion that is not exponentially bounded. Dulles Hall 012 Department of Mathematics math@osu.edu America/New_York public

Title:  Pre-H-fields and model companions

Speaker: Nigel Pynn-Coates - UIUC

Abstract: Pre-H-fields, introduced by Aschenbrenner and van den Dries in their work on the model theory of transseries and Hardy fields, provide a framework for studying the asymptotic behavior of real-valued functions at infinity from an algebraic and model-theoretic perspective. Together with van der Hoeven they showed that the theory of pre-H-fields has a model companion that is almost the theory of transseries, in particular, the model companion is "exponentially bounded" in a way that can be made precise. I will discuss a theory of pre-H-fields having a model companion that is not exponentially bounded.
