Inaugurated on December 17, 2017, the Institute for Advanced Study in Mathematics at Zhejiang University aims to provide a tranquil and stimulating environment in which mathematicians from all corners of the world can get together to work, think, and exchange ideas. The Institute has a substantial annual budget provided by Zhejiang University, supplemented by donations and government grants. Surrounded by a lovely forest garden, the institute’s newly-renovated interim building has a usable...

The Banff International Research Station (BIRS) addresses the imperatives of collaborative and cross-disciplinary research with a focus on the mathematical sciences and their vast array of applications in the sciences and in industry. Its modus operandi facilitates intense and prolonged interactions between scientists in a secluded environment, complete with accommo dation and board, and the necessary facilities, for uninterrupted research activities in a variety of formats, all in a magnificent mountain setting. BIRS embraces all aspects of the mathematical, computational and statistical sciences from the most fundamental challenges of pure and applied mathematics, theoretical and applied computer science, statistics, and mathe matical physics, to financial and industrial mathematics, as well as the mathematics of information technology, and the life sciences.Inaugurated in 2003, BIRS is a joint Canada-US-Mexico initiative that came about as the result of a remarkably concerted effort led, at the outset of the new millennium, by the Pacific Institute for the Mathematical Sciences (PIMS, Canada) and the Mathematical Sciences Research Institute (MSRI, Berkeley, USA), along with the support of the Mathematics of Information Technology and Complex Systems Network of Centres of Excellence (MITACS, Canada). IASM became the second BIRS Partnership Institutions in 2019. There will be 10 IASM-BIRS workshops in Hangzhou every year.

Time: 16:00-17:00, Wednesday, May 14 Title: A new proof of the arithmetic Siegel–Weil formulaSpeaker: Yu Luo 罗渝 (University of Wisconsin–Madison)Abstract: The arithmetic Siegel–Weil formula establishes a profound connection between intersection numbers in Shimura varieties and the Fourier coefficients of central derivatives of Eisenstein series. This result was proven by C. Li and W. Zhang in 2021 using local methods. In this talk, I will present a new proof of the formula that uses the local-global compatibility and the modularity of generating series of special divisors.

Time: 16:00-17:00, Wednesday, April 30 Title: Compactifications of subschemes of integral models of Hodge-type Shimura varietiesSpeaker: Shengkai Mao 毛盛开 (Chinese Academy of Sciences)Abstract: The special fiber of the integral model of a Hodge-type Shimura variety with parahoric level structure admits several natural stratifications that reflect the geometry of the associated universal abelian scheme. In this talk, I will present some new results on the compactification theory of such integral models constructed by Keerthi Madapusi, and describe the boundary behavior of various strata, including central leaves, Newton strata, Kottwitz–Rapoport strata, and Ekedahl–Kottwitz–Oort–Rapoport strata. This latter work builds on and generalizes some work by Kai-Wen Lan and Benoît Stroh.

Time: 11:00-12:00, Friday, April 25Title: Integral Hecke correspondences and what I learned from studying themSpeaker: Michael Rapoport (Universität Bonn)Abstract: I will explain more details of our approach to the problem raised in the colloquium talk. (FYI) Colloquium abstract: Shimura varieties are algebraic varieties over a number field. A characteristic feature of them is the abundance of self-correspondences, given by the so-called Hecke correspondences. In the theory of Shimura varieties the construction of integral models has seen a lot of activities over the years. However, the construction of integral models of Hecke correspondences is still in its infancy. I will explain the problem and some recent progress (joint work with Ulrich Gortz and Xuhua He).

Computation of the Grothendieck group of 1-cycles. Abstract: We now use generic transversality to compute the Grothendieck group of *semi-Fano* 1-cycles in complex threefolds.The argument is modelled on Ionel--Parker's proof of the Gopakumar--Vafa integrality conjecture. The main sticking point is to figure out how to leverage the weaker version of generic transversal...

Generic transversality in complex geometry.Abstract: A well known elementary property of pseudo-holomorphic curves in almost complex manifolds is *generic transversality*: simple (i.e. not multiply covered) pseudo-holomorphic maps are transverse (that is, unobstructed) for generic almost complex structures on a given target manifold.The corresponding assertion for complex structures is f...

Bivariant theories and the Grothendieck group of 1-cycles. Abstract: I will recall bivariant theories, which assign to a map X-->Y a group capturing the cohomology of Y with coefficients in fiberwise homology of X-->Y (or the reverse). Then I will show how to define the (very tautological) Grothendieck group of 1-cycles in complex threefolds based on these groups.&...
