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
Nero Budur, Robin van der Veer, Lei Wu +1
We prove a conjecture of the first author relating the Bernstein-Sato ideal of a finite collection of multivariate polynomials with cohomology support loci of rank one complex loca…
Hyperbolicity for log smooth families with maximal variation
Chuanhao Wei, Lei Wu
We prove that the base space of a log smooth family of log canonical pairs of log general type is of log general type as well as algebraically degenerate, when the family admits a…
