Abstract:

We present various realizations of classical braid groups from the viewpoints of algebra, geometry, and topology, along with their corresponding generalizations. In particular, we introduce a new construction of braid groups based on cluster combinatorics. Finally, we outline our novel realization of non-exceptional braid groups of Dynkin/Euclidean type as fundamental groups of moduli spaces.
