Analytic Criteria for Detecting Bernstein-Sato Roots

Yifan Chen, Huaiqing Zuo

We study roots of Bernstein-Sato polynomials of ideals. Our first main result gives a general partial differential equation criterion for detecting roots of the Bernstein-Sato poly…

Compact Kähler surfaces with semipositive anticanonical bundle

Yifan Chen, Simion Filip, Song Sun +2

We classify compact Kähler surfaces with semipositive anticanonical bundle. In particular, we resolve a question of Demailly--Peternell--Schneider: any blowup of at…

ALH Gravitational Instantons and Rational Surfaces

Yifan Chen, Chunhui Wei

We construct complete ALH hyperkähler metrics on complements of anticanonical elliptic curves with zero self-intersection in smooth rational surfaces. This answers the existence qu…

A Polynomial PDE Criterion for the Root of the Bernstein-Sato polynomial of Homogeneous Ideals

Yifan Chen, Huaiqing Zuo

Let be an ideal generated by homogeneous polynomials of a common degree . We give a polynomial partial differential equation criterion guar…

Numerical Godeaux Surfaces with many disjoint -curves and Applications

Yifan Chen, YongJoo Shin

In this paper, over the field of complex numbers, we prove that a numerical Godeaux surface contains at most six pairwise disjoint -curves, and that this bound is sharp. As a…

On the monodromy conjecture for determinantal varieties

Yifan Chen, Huaiqing Zuo

This paper presents a proof of the monodromy conjecture for determinantal varieties. Our strategy centers on an in-depth analysis of monodromy zeta functions, leveraging a generali…

On jet closures of singularities

Yifan Chen, Huaiqing Zuo

The jet closure and jet support closure were first introduced by de Fernex, Ein and Ishii to solve the local isomorphism problem. In this paper, we introduce two local algebras ass…

Smooth minimal surfaces of general type with and involutions

Yifan Chen, YongJoo Shin, Han Zhang

Lee and the second named author studied involutions on smooth minimal surfaces of general type with and . They gave the possibilities of the birational mode…

Hilbert series of second order jets of determinantal varieties

Yifan Chen, Yongxin Xu, Huaiqing Zuo

In this paper, we will investigate the jet schemes of determinantal varieties. It is quite often the case that the geometric information concerning the jet schemes of an algebraic…

On jet schemes of determinantal varieties

Yifan Chen, Huaiqing Zuo

Determinantal varieties are important objects of study in algebraic geometry. In this paper, we will investigate them using the jet scheme approach. We have found a new connection…

On Stringy E-functions and the Non-negativity Conjecture for Determinantal Varieties

Yifan Chen, Huaiqing Zuo

We compute the stringy E-functions of determinantal varieties and establish that the stringy E-function of a determinantal variety coincides with the E-function of the product of a…

On Kähler-Einstein Currents

Yifan Chen, Shih-Kai Chiu, Max Hallgren +3

We show that a general class of singular Kähler metrics with Ricci curvature bounded below define Kähler currents. In particular the result applies to singular Kähler-Einstein metr…

Mori dream spaces and Q-homology quadrics

Paolo Cascini, Fabrizio Catanese, Yifan Chen +1

We show that Shavel type surfaces are fake quadrics of even type which are not Mori dream surfaces, yet there are infinitely many primes such that the reduction modulo is a…

On Motivic Zeta Functions and Stringy E-function via Embedded -Resolution

Yifan Chen, Quan Shi, Huaiqing Zuo

We provide the formula of motivic zeta function for semi-quasihomogeneous singularities and in dimension two, we determine the poles of zeta functions. We also give another formula…
