Characteristic cycles associated to holonomic -modules
Lei Wu
We study relative and logarithmic characteristic cycles associated to holonomic -modules. As applications, we obtain: (1) an alternative proof of Ginsburg's log charact…
Bernstein-Sato ideals and hyperplane arrangements
Lei Wu
We study the relation between zero loci of Bernstein-Sato ideals and roots of b-functions and obtain a criterion to guarantee that roots of b-functions of a reducible polynomial ar…
Isotriviality of smooth families of varieties of general type
Chuanhao Wei, Lei Wu
In this paper, we proved that a log smooth family of log general type klt pairs with a special (in the sense of Campana) quasi-projective base is isotrivial. As a consequence, we p…
On the comparison of nearby cycles via -functions
Lei Wu
In this article, we give a simple proof of the comparison of nearby and vanishing cycles in the sense of Riemann-Hilbert correspondence following the idea of Beilinson and Bernstei…
Zero loci of Bernstein-Sato ideals -- II
Nero Budur, Robin van der Veer, Lei Wu +1
We have recently proved a precise relation between Bernstein-Sato ideals of collections of polynomials and monodromy of generalized nearby cycles. In this article we extend this re…
