Representation theory of quantum affine algebras via tensor products of modules over hereditary algebras
We introduce new families of monoidal structures suited to categorifying important invariants arising in the representation theory of quantum affine algebras and in the theory of cluster algebras. Our framework builds on Auslander–Reiten theory and higher homological algebra; namely, for each finite acyclic quiver \(Q\), we construct a monoidal category \(\mathcal{R}_Q\) whose indecomposable …

When Lawvere Meets Noether: A Logical Approach to Categorical Algebra and Isomorphism Theorems
Lawvere doctrines are a fundamental notion in categorical logic, providing a unified framework for the study of logical systems and their categorical semantics. Several important classes of categories, including regular categories and elementary toposes, admit characterizations in terms of doctrines satisfying suitable properties. However, the potential of this framework in categorical algebra …
