Algebraic structures behind Hilbert schemes and wreath products
Weiqiang Wang
In this paper we review various strikingly parallel algebraic structures behind Hilbert schemes of points on surfaces and certain finite groups called the wreath products. We expla…

Twisted vertex representations via spin groups and the McKay correspondence
Igor Frenkel, Naihuan Jing, Weiqiang Wang
We establish a twisted analog of our recent work on vertex representations and the McKay correspondence. For each finite group and a virtual character of we construct twist…

Virasoro algebra and wreath product convolution
Igor Frenkel, Weiqiang Wang
We present a group theoretic construction of the Virasoro algebra in the framework of wreath products. This can be regarded as a counterpart of a geometric construction of Lehn in…
