Conference: Young Topologists Meeting 2022

2022年青年拓扑学家会议（YTM）将于2022年7月18日星期一至7月22日星期五在哥本哈根大学举行。YTM由两个主要部分组成：一方面是由杰出研究人员提供的三门迷你课程，另一方面是由40个简短演讲和20个海报展示组成的系列，主要是研究生。作为世界上致力于代数拓扑领域早期职业研究人员的最大会议之一，YTM为初级拓扑学家提供了一个独特的机会，让他们获得向广大听众发表会议演讲的经验，通过学习他们所在机构没有代表的子领域来拓宽视野，将他们的工作展示给国际拓扑学社区，并与其他早期职业研究人员发展合作。此外，YTM旨在通过邀请来自代表性不足的群体和在拓扑学中代表性较低的大学的研究生演讲者，并为来自所有背景的学生提供一个友好和热情的社区，从而促进多样性。通过为美国参与者提供资金，NSF正在促进美国与国际拓扑学社区之间的科学思想交流，特别是为来自美国的学生和其他拓扑学家提供一个与未来的国际同事建立研究联系和发展关系的环境，以及支持多样性和包容性的文化。今年的三门迷你课程将是：(1)Andrew Blumberg的辛同伦理论，他将介绍Floer稳定同伦理论，并着眼于他最近与Mohammed Abouzaid在Arnold猜想上的突破；(2) Natalia Castellana的分层和下降，围绕她和合作者最近在代数拓扑和表示理论中感兴趣的各种空间的协链上模类的支持分层的一系列论文；(3) Robert Ghrist的细胞束理论，这将是应用拓扑中束理论的速成课程，从细胞束的基本材料开始，然后转向拓扑数据分析中的各种用例。这些迷你课程提供了对当前活跃研究的主要子领域的介绍，甚至作为早期研究生进入这些领域的门户。与会者贡献的演讲和海报将涵盖广泛的拓扑主题，跨越高等代数，同伦理论，几何和应用拓扑。更多信息可从会议网站https://www.math.ku.dk/english/calendar/events/ytm2022/This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知识价值和更广泛的影响审查标准进行评估，被认为值得支持。

The Young Topologists Meeting (YTM) 2022 will be held at the University of Copenhagen from Monday, July 18, to Friday, July 22, 2022. The YTM consists of two major components: three mini-courses by distinguished researchers on the one hand, and a line-up of forty short talks and twenty poster presentations, mostly by graduate students, on the other. Being one of the largest conferences in the world dedicated to early career researchers in the field of Algebraic Topology, the YTM provides a unique opportunity for junior topologists to gain experience giving conference presentations to a wide audience, broaden their horizons by learning about subfields not represented at their institutions, expose their work to the international topology community, and develop collaborations with other early career researchers. Furthermore, the YTM seeks to promote diversity by featuring graduate student speakers from underrepresented groups and from universities that are less well-represented in topology and by providing a friendly and welcoming community for students from all backgrounds. By providing funding for US participants, the NSF is promoting the exchange of scientific ideas between the US and the international topology community, in particular providing a setting for students and other topologists from the US to make research connections and develop relationships with their future international colleagues, as well as supporting a culture of diversity and inclusion. The three mini-courses this year will be on: (1) symplectic homotopy theory by Andrew Blumberg, which will provide an introduction to Floer stable homotopy theory with an eye towards his recent breakthrough with Mohammed Abouzaid on the Arnold conjecture; (2) stratification and descent by Natalia Castellana, revolving around a recent series of papers by her and coauthors on the support-stratifications of module categories over cochains of various spaces of interest in algebraic topology and representation theory; and (3) cellular sheaf theory by Robert Ghrist, which will be a crash course on sheaf theory in applied topology, starting with basic materials on cellular sheaves and moving on to various use-cases in topological data analysis. These mini-courses offer introductions into major subfields of current active research, and serve as a gateway into these fields even for early graduate students. Participant-contributed talks and posters will cover a wide range of topics in topology, spanning across higher algebra, homotopy theory, geometry, and applied topology.
