Abstract
We consider derivations ∂ on Conway’s field No of surreal numbers such that the ordered differential field (No, ∂) has constant field ℝ and is a model of the model companion of the theory of H-fields with small derivation. We show that this determines (No, ∂) uniquely up to isomorphism and that this structure is absolutely homogeneous universal for models of this theory with constant field ℝ.
