Let $D\subset V=\mathbb{C}^n$ be a reductive linear free divisor, with defining equation $h$. Its logarithmic Brieskorn lattice is $(G_0(h),\nabla)$, and its spectrum at $\theta=0$…

Let $f$ be the linear free divisor considered in the paper, let $\mathbf{G}$ and $\overline{\mathbf{G}}$ be the corresponding Gauss–Manin systems, and let $G$ and $\overline{G}$ de…
