Generalized nearby cycles via relative and logarithmic $D$ -modules

Lei Wu, with an appendix by Claude Sabbah

For a regular map $F$ from a complex smooth affine variety $X$ to $A_{C}^{r}$ , we construct generalized nearby-cycle modules of a regular holonomic $D$ -module…

The Intersection Structure of Bernstein-Sato Ideals

Lei Wu

By using logarithmic $D$ -modules and GrÃ¶bner bases, we prove that Bernstein-Sato ideals satisfy some symmetric intersection property, answering a question posed by Budur.…

A Note on a Recent Attempt to Prove the Irrationality of $I^¶ (5)$

Keyu Chen, Wei He, Yixin He +7

Recently Shekhar Suman [arXiv: 2407.07121v6 [math.GM] 3 Aug 2024] made an attempt to prove the irrationality of $I^¶ (5)$ . But unfortunately the proof is not correct. In this note, w…
