The Jacobian of Modular FormsIt is an important problem in the theory of modular forms to determine the structure of rings of modular forms, that is, to find explicit generators and their relations. In this talk, I will introduce the modular Jacobian approach to construct and cla...王好武 博士 （韩国浦项基础科学研究所）腾讯会议室2021年12月24日（星期五） 10:00–11:00

Minimal Graphs and Related Flows in Warped Product ManifoldsIn this talk we report our series of results on minimal graphs and related problems in warped product (WP) manifolds. Our motivation is to view WP manifolds as canonical manifolds in the certain sense. Then we introduce our result...周恒宇 副研究员 （重庆大学）腾讯会议室2021年12月24日（星期五） 14:00—15:00

Multi-Modes Method,Ensemble Method,and Multi-Scale Method for Random PDEs and...In this talk, I shall first discuss a newly developed multi-modes Monte Carlo method for solving random PDEs, both random diffusion equations and random wave equations (in frequency domain) will ...凤小兵 教授 (田纳西大学)腾讯会议室2021年12月20日（星期一） 9:00-11:00

On Numerically Trivial Automorphisms of Threefolds of General TypeIn studying automorphism groups of projective varieties X, it is a basic problem to understand its induced action on the cohomology groups, say with rational coefficients. We call an automorphism σ∈Aut(X) numerically trivial, if it...刘文飞 教授 (厦门大学)腾讯会议室2021年12月17日（星期五） 8:30-9:30

On the Multiscale Landau-Lifshitz-Gilbert EquationPermalloy is a nickel-iron magnetic alloy, which typically has a face-centered cubic phase but may form an irregular polycrystalline structure. Its magnetization dynamics is modeled by the multiscale Landau-Lifshitz-Gilbert (LLG) equation ...陈景润 教授 (中国科学技术大学)腾讯会议室2021年12月17日（星期五） 晚8:00-9:00

On the Semistable Reductions of Hyperelliptic CurvesGiven a surface fibration over ℂ of genus , the semistable reduction theorem asserts there is a finite morphism so that the base change of over admits a semi-stable model. The smallest degree, denoted by , of all such is called the stable inde...顾怡 副教授 (苏州大学)腾讯会议室2021年12月17日（星期五） 11:00-12:00

Sheaves on Non-Reduced Curves in a Projective SurfaceSheaves on non-reduced curves can appear in moduli spaces of 1-dimensional semistable sheaves over a surface, and moduli spaces of Higgs bundles as well. We estimate the dimension of the stack M_X(nC, \chi) of pure sheaves supported at the non...袁瑶 教授 (首都师范大学)腾讯会议室2021年12月17日（星期五） 9:45-10:45

Centre-Augmented L2-Type Regularization for Subgroup LearningThe existing methods for subgroup analysis can be roughly divided into two categories: finite mixture models (FMM) and regularization methods with an L1 -type penalty. In this paper, by introducing the group centres a...林华珍 教授 （西南财经大学 国家杰青）腾讯会议室2021年12月17日（星期五） 下午16:00-17：00
