Zapraszamy na seminarium wydizłowe 11.06.2024 (wtorek) o godz. 12.00 w sali A.1.3 w budynku C-19. Wykład Analysis on buildings: how and why? wygłosi: prof. Bertrand Rémy z École normale supérieure de Lyon.
Abstract: Harmonic analysis on symmetric spaces is a well-established topic having connections with many different fields in mathematics: geometry, representation theory, number theory for instance. Affine buildings are metric spaces playing a complementary role from this perspective: symmetric spaces are associated with simple real Lie groups, while affine buildings correspond to non-Archimedean Lie groups. Nowadays, without necessarily referring to any group action, it is possible to develop a useful version of harmonic analysis on these singular non-positively curved spaces. Our primary goal will be to introduce the most basic objects and then to provide some motivations for and applications of the theory.
