T-convex T-differential fields and their immediate extensions

Submission date: 22 April 2021


Let T be a polynomially bounded o-minimal theory extending the theory of real closed ordered fields. Let K be a model of T equipped with a T-convex valuation ring and a T-derivation. If this derivation is continuous with respect to the valuation topology, then we call K a T-convex T-differential field. We show that every T-convex T-differential field has an immediate strict T-convex T-differential field extension which is spherically complete. In some important cases, the assumption of polynomial boundedness can be relaxed to power boundedness.
