Abstract: | Let (K, ∥ · ∥) be a valued transcendence degree 1 extension of p. An element x ∈ K transcendental over p is said to have order ≤a (a > 0) if there exists Cx > 0 such that every polynomial P(X) ∈ p X] satisfies when ∥ · ∥ is the Gauss norm on pX]. No x ∈ p can have order ≤α if α < 1 but we construct some x ∈ p with order ≤ 1. Furthermore, we prove order ≤α is stable by algebraic extension. |
