报告题目: Spin coinvariant algebras and spin fake degrees for Weyl groups

报告内容：The coinvariant algebra of a Weyl group W is a graded regular representation of W. The graded multiplicities of simple W-modules in a coinvariant algebra are known as fake degrees and have been computed by Lusztig and others. We formulate the notion of spin coinvariant algebra for a double cover $\tilde{W}$ of every Weyl group W, and determine all the spin fake degrees, i.e., the graded multiplicity of spin simple modules of $\tilde{W}$. This talk is based on the Virginia dissertation of Constance Baltera.
