报告题目:Yang-Mills-Higgs-Schrödinger flow
报告摘要:In this talk, we introduce the Yang-Mills-Higgs-Schrödinger flow, an infinite-dimensional Hamiltonian flow associated with the Yang-Mills-Higgs functional defined on a holomorphic fiber bundle. This flow naturally generalizes the Schrödinger flow proposed by Ding and Wang to a gauged setting. We explore its geometric structures and establish local well-posedness results. This is joint work with Chong Song.

报告题目:Multiplicity of solutions to strongly indefinite equations with concave-convex nonlinearities
报告摘要:The aim of this report is to explore the existence and multiplicity of stationary solutions to the strongly indefinite equations with concave-convex nonlinearities. According to a generalized linking argument about the strongly indefinite functional, we prove that there exist two sequences of solutions to the strongly indefinite equations with positive and negative energy respectively.

报告题目:The Elliott-Halberstam Conjecture from a Nonlinear Analytic Perspective
报告摘要:The Elliott-Halberstam Conjecture, a central statement concerning the distribution of primes in arithmetic progressions, has traditionally been studied via analytic number theory and sieve methods. In this talk, we explore the conjecture through the lens of nonlinear analysis, recasting its core estimates as functional bounds over high-dimensional, nonlinearly structured parameter spaces. By constructing a functional analytic framework that reflects the behavior of error terms in prime counting functions, we highlight deep analogies with problems in harmonic and nonlinear PDE theory, such as energy functional control, multiscale averaging, and stability under perturbations. This approach not only bridges conceptual gaps between additive number theory and analysis, but also suggests new mathematical strategies for understanding average-case error distributions in sieve theory. Our perspective is motivated by recent developments in additive combinatorics, spectral methods, and the work of Zhang, Maynard, and Tao on bounded prime gaps.

报告摘要:Burgos Gil, Menares and Rivera-Letelier computed the essential minimum of Faltings height of elliptic curves up to five decimal places. We shall give several remarks, based on recent breakthroughs of the theory of adelic line bundles on quasi-projective varieties of Yuan-Zhang and the equidistribution theorem of algebraic integers of Smith and Orloski-Sardari.

报告题目:Homotopy Theory of Nijenhuis Lie Algebras
报告摘要:The Nijenhuis structure has significant applications in geometry. In this talk, we will explore the deformation theory of Nijenhuis Lie algebras from an algebraic perspective. We will present an L-infinity algebra that controls the deformations of Nijenhuis Lie algebras. Moreover, it will be revealed that this L-infinity algebra is essentially provided by the minimal model of the operad of Nijenhuis Lie algebras. Consequently, we introduce higher versions of Nijenhuis Lie algebras, namely homotopy Nijenhuis Lie algebras. Additionally, we will investigate the connection between our construction and the profile of Nijenhuis geometry introduced by Merkulov.

报告题目:Parabolic Hitchin systems of type D
报告摘要:Hitchin system is an interesting object at the intersection of algebraic geometry, geometric representation and mathematical physics. We will mainly talk about the parabolic Hitchin system system in type D, especially the generic fibers and the Hitchin base. We show that the parabolic Hitchin fiber is a torsor of a self-dual abelian variety if and only if the associated nilpotent orbit is special, which is an important concept introduced by Lusztig in the study the geometric representation nature of the nilpotent orbits. Meanwhile, we also give a concrete description of the Hitchin base of parabolic Hitchin systems in type D. Surprisingly, when we insert the information of cotangent bundle of a flag variety to the Hitchin system, then the Hitchin base contains some new functions more that the coefficients of the characteristic polynomial in type D. We call these new functions by “new pfaffians” following Donagi. We give a comprehensive construction for all the “new pfaffians” and then show the Hitchin base is an affine space in this case. This talk is based on an on-going work with Yaoxiong Wen and Bin Wang.

报告题目:Compact moduli spaces of sheaves on a curve
报告摘要: It is a classical result that the semistable vector bundles on a curve form a compact moduli space. In a joint work with Andres Fernandez Herrero and Dario Weissmann, we show this is the only open condition on families of sheaves that yields a compact moduli space. This is based on the preprint arXiv: 2504.11155.
