*讲座内容简介:
We will discuss a general construction of the Sugawara operators for the quantum affine algebra of type A. In 2016, we gave an explicit construction of the Sugawara operators in terms of certain traces over a tensor products associated with antisymmetrizers of the Hecke algebra. In this talk, we generalize the construction and construct central operators associated with any primitive idempotents of the Hecke algebra. If time permits, I will talk about the Harish-Chandra images of the Sugawara operators and identify them with the eigenvalues of the operators acting on the q-deformed Wakimoto modules. This is joint work with M. Liu and A. Molev.
