Forschungsseminar Geometrie und Topologie

Summer Term 2022

Prof. Dr. Holger Reich - Prof. Dr. Elmar Vogt - Dr. Gabriel Angelini-Knoll

  • Time and place: Tuesday, 14--16h, online.
    When in presence then SR024, Arnimallee 3. 

Content: Talks by masters and Phd students about ongoing work and selected research topics as well as guest talks.

This summer term our selected research topic will cover the field of
Hermitian K-theory
Groundbreaking work of Calmès, Dotto, Harpaz, Hebestreit, Land, Moi, Nardin, Nikolaus, and Steiml has had a big impact on the study of surgery theory and Grothendieck-Witt groups. The goal of this seminar is understand the machinery developed in the papers Hermitian K-theory for stable infinity categories parts I and II by these nine authors.
