Umiddelbart forud for generalforsamlingen, kl 16:15, afholder vi et foredrag ved Fabrice Baudoin (AU) i lokale U49A: https://clients.mapsindoors.com/sdu/573f26e4bc1f571b08094312/details/563cb8e9423b7d0540c9a2b6.
Fabrice arbejder i overlappet mellem stokastik, analyse og geometri. Han har for nylig modtaget såvel en Villum Investigator-bevilling såvel som et ERC Advanced Grant. Fabrice har skrevet følgende abstract for foredraget.
Fractals are geometric objects with intricate structure at every scale. Although they are easy to conceptualize, they are difficult to study analytically because they are non-smooth spaces: there are no tangent planes and no obvious notion of derivatives. Nevertheless, one can still develop key tools of analysis on fractals. In this talk I will explain how we construct analogues of the Laplacian and the heat equation on certain fractal sets. The main idea is to approximate the fractal by finite graphs, define energies and Laplacians on these discrete objects, and then pass to a limit. This approach leads to a notion of diffusion on fractals and naturally gives rise to Brownian motion adapted to their geometry. The resulting processes behave in ways that are strikingly different from diffusion in ordinary Euclidean space. The goal of the talk is to give a conceptual overview of how analysis can be developed even in the absence of smooth structure.
Alle – medlemmer af DMF såvel som interesserede – er velkomne til foredraget. Til generalforsamlingen er kun medlemmer inviteret.
