Abstract： The theory of characteristic classes of the projective unitary group PU(n) is fundamental yet very mysterious as of today. We will review recent progresses on the study on this topic, an
三月 清华大学求真书院第三届Pi节挑战赛圆满举办 为纪念中国古代数学家祖冲之，国际数学协会从2011年开始将每年的3月14日设为国际数学节，也称为国际圆周率日。在这具有纪念意义的日子，求真书院成功举办了第三届...
Abstract： We establish global well-posedness and convergence of the score-based generative models (SGM) under minimal general assumptions of initial data for score estimation. For the smooth case,...
Abstract We use the Hamiltonian reduction method to construct the Ruisenaars dual systems togeneralized Toda chains associated with the classical Lie algebras of types B, C, D. The dualsystems tumn
Abstract We construct 7D SymTFTs associated to 6D SCFTs via compactification of llB SUGRA with 7-branes on non-compact geometries. We find that the reduction of the topological action of llB
Abstract： The mean curvature flow is an example of a geometric flow, where in this case one deforms a submanifold according to its mean curvature vector. Like many such flows though the mean
Speaker Intro Sergio Cecotti graduated in physics at the University of Pisa in 1979 and has worked at the Harvard University, the University of Pisa, CERN, etc.. In 2014, he became a full professor
Abstract： In this talk, we will discuss linear equivalences between cuspidal divisors on the moduli stack of Drinfeld shtukas. We exhibit explicit linear equivalences with the help of auxiliary
