Anderson generating function of rank-one Drinfeld Module over rational function fields

Chuangqiang Hu, Xiao-Min Huang, Stephen S. -T. Yau

We establish a fundamental breakthrough in rank-one Drinfeld module arithmetic by deriving explicit formulas over the integral domain $\A = H^{0}(\mathbb{P}^1-P_ρ, \mathcal{O}_{\m…

Nakai conjectures for isolated weighted homogeneous hypersurface singularities

Stephen S. -T. Yau, Qiwei Zhu, Huaiqing Zuo

The long-standing Nakai Conjecture concerns a very natural question: can differential operators detect singularities on algebraic varieties? On a smooth complex variety, it is well…

Classification of unimodal isolated complete intersection singularities in positive characteristic

Hongrui Ma, Stephen S. -T. Yau, Huaiqing Zuo

In this paper we classify the unimodal isolated complete intersection singularities in arbitrary characteristic under contact equivalence. The classification over has…

Regularity estimate and sparse approximation of pathwise robust Duncan-Mortensen-Zakai equation

Yuhua Meng, Zhongjian Wang, Stephen S. T. Yau +1

In this paper, we establish an \textit{a priori} estimate for arbitrary-order derivatives of the solution to the pathwise robust Duncan-Mortensen-Zakai (DMZ) equation within the fr…
