Abstract
Reformulating symmetries as a subsector of quasi-topological defects of various codimensions generalizes the notion of symmetry group to a symmetry fusion algebra (or a categorical symmetry). Sometimes, such fusion algebras organize nicely in 2-group structures. 2-group symmetries are ubiquitous in the landscape of field theories: these have been found in simple theories such as QED, as well as in some of the most exotic like 6d little strings. In this seminar we will discuss some applications of geometric engineering techniques in M-theory to unravel these structures for theories without a Lagrangian formulation.
