Resumen de On a differential intermediate value property
Matthias Aschenbrenner, Lou van den Dries, Joris van der Hoeven
Liouville closed H-fields are ordered differential fields where the ordering and derivation interact in a natural way and every linear differential equation of order 1 has a nontrivial solution. (The introduction gives a precise definition.) For a Liouville closed H-field K with small derivation we show that K has the Intermediate Value Property for differential polynomials if and only if K is elementarily equivalent to the ordered differential field of transseries. We also indicate how this applies to Hardy fields.
