Okutsu sequences in Henselian fields

For $(K,v)$ a Henselian valued field, let θ̄ with minimal polynomial F over K. Okutsu sequences of θ have been defined only when the extension K(θ)/K is defectless. In this paper, we extend this concept to arbitrary θ̄ and we show that these objects are essentially equivalent to Okutsu frames of F and to Mac Lane-Vaqui\'e chains of the natural valuation on $K[x]$ induced by θ.
