讲座简介：In this talk, I will report some new results on the classification of real simple modules over a simply-laced quantum affine algebra and categorifications of cluster algebras. Let C be the category of finite-dimensional modules over a simply-laced quantum affine algebra Uq(g). For certain small subcategories of C whose Grothendieck rings admit cluster algebra structures of finite type, we completely classify all real simple modules in terms of their highest ell-weight monomials. The real simple modules of type D and type E are new, and our treatment for type A is different with the one of Brito-Chari. We are using our method to study more real simple modules. This is ongoing joint work with Professor Ralf Schiffler.
