Shinichiroh Matsuo : Gysin maps and bulk-edge correspondence
Abstract: We propose a yet another definition of KR-groups, which combines those of Atiyah and Karoubi and gives a simple proof of the Bott periodicity. Using the new definition, we can formulate the bulk-edge correspondence for free fermion systems as the functoriality of the Gysin map. T

Max Karoubi: Algebraic maps between spheres and Bott periodicity
The lecture was held within the framework of the Hausdorff Trimester Program: K-Theory and Related Fields. At the beginning of his research, J.-L. Loday proved that an algebraic map between an n-dimensional torus and an n-sphere is necessarily homotopic to a constant map. We generalize th

Yonatan Harpaz - New perspectives in hermitian K-theory II
Warning: around 32:30 in the video, in the slide entitled "Karoubi's conjecture", a small mistake was made - in the third bulleted item the genuine quadratic structure appearing should be the genuine symmetric one (so both the green and red instances of the superscript gq should be gs), an
