Okutsu frames of irreducible polynomials over henselian fields
For a henselian valued field $(K,v)$ we establish a complete parallelism between the arithmetic properties of irreducible polynomials $F\in K[x]$, encoded by their Okutsu frames, and the valuation-theoretic properties of their induced valuations $v_F$ on $K[x]$, encoded by their MacLane-Vaquié chains. This parallelism was only known for defectless irreducible polynomials.
