Mathematical structures in algebra, geometry and logic ****************************************************************************************** * Mathematical structures in algebra, geometry and logic ****************************************************************************************** Foundations of the research in algebra, geometry and logic at the Faculty were laid in the Eduard Čech and Petr Vopěnka. Over the past decade, activities of the Eduard Čech Institut Excellence (ECI and ECC) have fostered research in these areas. Since 2018, the seven year University Research Center (UNCE) project “Methods in Algebra a is running at the Faculty, headed by a renown expert in proof complexity, Jan Krajíček [ U www.karlin.mff.cuni.cz/~krajicek/"] . Applications of universal algebra to constraint sati are a major topic pursued by the group of Libor Barto [ URL "http://www.karlin.mff.cuni.cz the support by his CoCoSym [ URL "https://cordis.europa.eu/project/rcn/213446/factsheet/en Grant of the ERC. Algebraic topics include representation theory, and its connections to h (Jan Šťovíček [ URL "https://www.karlin.mff.cuni.cz/~stovicek/index.php/en/homepage"] ) an homological algebra (Jan Šaroch). Since 2019, the five year EXPRO project “Homotopy and ho and tools related to mathematical physics’’ is financed by GAČR. It includes research in a (Petr Somberg [ URL "http://www.karlin.mff.cuni.cz/~somberg/"] ), differential geometry (V [ URL "http://www.karlin.mff.cuni.cz/~soucek/"] ), and applications in theoretical physics Jurčo). ****************************************************************************************** * Selected outputs ****************************************************************************************** • Barto, L.
