  This mini-course, conducted at the XI School on Geometric, Algebraic, and
Topological Methods in Quantum Field Theory held in Villa de Leyva, Colombia,
provides an overview of the interconnection between generalized symmetries and
cohomology. It is designed for advanced undergraduate students with a
background in physics or mathematics. Additionally, we describe a method for
connecting generalized symmetries with cobordisms and K-theory within the
framework of string theory. We assume basic knowledge in quantum field theory
and differential forms.
