该奖项为2018年5月9日至12日在俄亥俄州哥伦布市的俄亥俄州立大学举办的舒伯特微积分研讨会的参与者提供旅行和住宿支持。会议的主题起源于19世纪的列举几何,当时数学家计算出满足各种条件的几何图形的数目。这门学科成长为交集理论的试验场,而交集理论现在是现代数学的基石。这次研讨会将汇集来自不同背景的研究人员和学生,就舒伯特演算这一主题提出不同的观点。舒伯特演算的很大一部分内容涉及Grassmannians和FLAG流形的上同调环及其推广。这门学科与组合学、表示论和代数几何有着深刻的联系,在过去的15年里,舒伯特微积分的技术取得了显著的发展。一个有指导意义的问题是找到旗形变种中Schubert类的乘法的组合公式;解决了这个问题的几个新情况。新的研究将我们对Schubert演算的理解扩展到无限维仿射(和Kac-Moody)旗簇,同时加深了与表示理论的联系。这次会议的主要目标包括分享新的成果,并向新一代学生介绍该领域的技术、应用和开放问题。有关研讨会的更多细节可在https://people.math.osu.edu/anderson.2804/schub2018.html.This网站上获得,该奖项反映了美国国家科学基金会的法定使命,并通过使用基金会的智力优势和更广泛的影响审查标准进行评估,被认为值得支持。
英文摘要
This award provides travel and lodging support for participants in a Workshop on Schubert Calculus, to take place May 9-12, 2018, at the Ohio State University in Columbus, Ohio. The topic of the conference has its origins in 19th century enumerative geometry, when mathematicians computed numbers of geometric figures satisfying various conditions. The subject grew into a testing ground for Intersection Theory, which is now a cornerstone of modern mathematics. This workshop will bring together researchers and students coming from different backgrounds, to present various points of view on the subject of Schubert Calculus.A large part of Schubert Calculus concerns the cohomology rings of Grassmannians and flag manifolds, as well as their generalizations. The subject has deep connections to combinatorics, representation theory, and algebraic geometry, and the last 15 years have seen remarkable developments in the techniques of Schubert Calculus. A guiding problem is to find combinatorial formulas for the multiplication of Schubert classes in flag varieties; several new cases of this problem were solved. New research has extended our understanding of Schubert calculus to the infinite-dimensional affine (and Kac-Moody) flag varieties, simultaneously deepening the connection with representation theory. Major goals of this conference include sharing new results and introducing a new generation of students to the techniques, applications, and open problems in the field. More details about the workshop are available at https://people.math.osu.edu/anderson.2804/schub2018.html.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.
