Representation Theory is all about studying abstract algebraic structures through linear transformations. You'll explore how groups, algebras, and other mathematical objects can be represented as linear transformations of vector spaces. The course covers topics like character theory, induced representations, and applications to physics and chemistry.

Is Representation Theory hard?

Representation Theory can be pretty challenging, not gonna lie. It requires a solid foundation in linear algebra and abstract algebra, which can be tough concepts to grasp. The abstract nature of the subject can make it feel like you're juggling invisible objects sometimes. But once things click, it's actually pretty cool to see how it ties together different areas of math.
