Abstract: Given a valued field (K,v), we say that a rational function f(x)
in K(x) is integral or infinitesimal definite on the definable set S
if v(f(b)) ≥ 0 or v(f(b))>0, respectively, for each b in S.
I will give algebraic characterizations of integral definite and
infinitesimal definite rational functions in various model-complete
theories of valued fields, analogous to the Positivstellensatz and
Negativstellensatz for real closed fields.
