What Do You Know About Highest-weight Categories?

10 Questions  Settings  In mathematics, the field of representational theory studies abstract algebraic structures by the using the linear transformation of vector spaces to represent their elements. The highest weight category is also one of this representational theory, it is a k-linear category, that has k as its field. This quiz will test your knowledge about the topic and introduce you to it if you are yet to know what it is.
