Spring semester 2025

In the spring semester, the main topic of the talks was the theory of Lie algebras and groups, their generalizations, and their applications in theoretical physics. In addition, there were two very interesting talks on operads and quasi-ideals of semigroups. The titles of the talks reflect the close collaboration between mathematicians and physicists within the seminar. This collaboration is based on the theory of Lie algebras. Lie groups are the mathematical expression of a fundamental property of matter — symmetry. It is precisely this that underlies their use in elementary particle physics.
