On Regular Mac Lane-Vaquié chains

Let $(K^h,v^h)$ be a Henselization of a valued field $(K,v)$, $μ$ any extension of $v$ to $K[x]$, and $μ^h$ the canonical extension of $μ$ and $v^h$ to $K^h[x].$ In this paper, we study two new invariants associated with a Mac Lane-Vaquié chain (MLV) of $μ$, namely, the defect of each augmentation s
