Explore the Kudla-Rapoport conjecture in this comprehensive lecture from the Joint IAS/Princeton University Number Theory Seminar. Delve into Hurwitz class numbers and their relations, examining a geometric proof of Hurwitz's formula and its reinterpretation. Investigate the connection to Eisenstein series of genus 2 and the Gross-Keating formula. Learn about the L-functions associated with the Kudla-Rapoport conjecture and gain insights into the current state of knowledge surrounding this mathematical problem. Examine the unitary Rapoport-Zink space and its geometry, as well as arithmetic intersection numbers. Understand the proof strategy involving induction, the uncertainty principle, and decomposition techniques. This in-depth talk by Chao Li from Columbia University offers a thorough exploration of this complex mathematical topic.
