|Quasisymmetric functions and weak Bruhat interval modules of the 0-Hecke algebras
※ 장소: 상산관 101호
Since the mid-2010s, there have been many attempts to construct modules of the 0-Hecke algebras categorifying important quasisymmetric functions using tableau models. Recently, to provide a unified method to handle these modules, I defined weak Bruhat interval modules with my collaborators. In this talk, I will introduce weak Bruhat interval modules and their structural properties. This is based on joint work with W.-S. Jung, S.-Y. Lee, and Y.-T. Oh.
