V tomto čtecím kurzu budeme používat homotopické metody jako například L_\infty and G_\infty struktury ke
kvantování geometrických struktur, mj. Poissonových bivektorů a r-matic. Hlavním cílem je získat vhled do slavné
Kontsevichovy Věty o formalitě a návazných prací Dolgusheva and Tamarkina o deformačním
kvantování. Dále budeme studovat kvantování dynamických r-matic pomocí Drinfel'dových asociátorů dle prací
Calaqua.
Poslední úprava: Šmíd Dalibor, Mgr., Ph.D. (19.05.2025)

The goal is to get familiar with the deformation problem arising from Poisson geometry, where Poisson bivectors constitute the semi-classical limit of star products. As a preparation, the necessary amount of differential geometry will be studied, specifically the Cartan calculus on smooth manifolds. The solution of the deformation problem, given by Kontsevich's formality theorem, further requires the notions of homotopy Lie algebra and the corresponding quasi-isomorphisms. On the algebraic side, the deformation theory of Gerstenhaber will give the formal background to understand the deformations of associative algebras from a general point of view. Globalization methods, in the sense of Dolgushev and Cattaneo-Felder, might be considered, as well. Poslední úprava: Weber Thomas, Ph.D. (25.09.2025)

The participants are expected to study a subject related to the direction of the course and present it in the second half of the semester. This can also be done in joint work with other participants. For interested students there might be the possibility to continue the course project in form of a master thesis. Poslední úprava: Weber Thomas, Ph.D. (25.09.2025)

Reading course, where the first lessons will be delivered by the lecturer and participants are supposed to contribute with short presentations in the second half of the semester. The course will also be streamed via Teams. Recordings, as well as lecture notes, will be made available on Teams and via email.
