Let $X$ be a complex variety, let $\mathcal{M}$ be a holonomic $\mathcal{D}$-module on $X$, and let $S(\mathcal{M})$ be the union, over germs of hypersurfaces $Z$ of $X$, of the se…

Let $X$ be a complex manifold and let $f$ be a holonomic $f$-module on $X$. For each hypersurface $Z$ of $X$, consider the analytic slopes of $f$ along $Z$, namely the real numbers…
