Homological algebra and representation theory form a powerful confluence in modern mathematics. Homological algebra provides a framework for analysing algebraic structures via chain complexes, ...

Representation theory was initially dismissed. Today, it’s central to much of mathematics. When representation theory emerged in the late 19th century, many mathematicians questioned its worth. In ...

Supercharacter theory offers a tractable refinement of classical character theory by consolidating characters and conjugacy classes into supercharacters and superclasses. Initially conceptualised to ...
