报告摘要:

Cuspidal modules play a central role in the classification of simple weight modules with finite-dimensional weight spaces. In this talk, we study cuspidal sl_{n+1}-modules through the minimal finite W-algebra. Using an explicit embedding into U(gl_n), we determine the reducibility and composition factors of restrictions of finite-dimensional simple gl_n-modules, showing that their length is at most two. We then realize every simple cuspidal sl_{n+1}-module as a simple quotient of a Shen–Larsson tensor module.
