Hilbert schemes and symmetric products: a dictionary
Zhenbo Qin, Weiqiang Wang
Given a closed complex manifold of even dimension, we develop a systematic (vertex) algebraic approach to study the rational orbifold cohomology rings $\orbsym$ of the symmetri…
Hilbert schemes and W algebras
Wei-Ping Li, Zhenbo Qin, Weiqiang Wang
We construct geometrically the generating fields of a W algebra which acts irreducibly on the direct sum of the cohomology rings of the Hilbert schemes of n points on a projective…
Stability of the cohomology rings of Hilbert schemes of points on surfaces
Wei-Ping Li, Zhenbo Qin, Weiqiang Wang
We establish some remarkable properties of the cohomology rings of the Hilbert schemes of n points on a projective surface X, from which one sees to what extent these cohomology ri…
Twisted vertex representations and spin characters
Naihuan Jing, Weiqiang Wang
We establish a new group-theoretic realization of the basic representations of the twisted affine and twisted toroidal algebras of ADE types in the same spirit of our new approach…
Equivariant K-theory, generalized symmetric products, and twisted Heisenberg algebra
Weiqiang Wang
For a space X acted by a finite group $\G$, the product space affords a natural action of the wreath product $\Gn$. In this paper we study the K-groups $K_{\tG_n}(X^n)$ of $\…
Lie subalgebras of differential operators on the super circle
Shun-Jen Cheng, Weiqiang Wang
We classify anti-involutions of Lie superalgebra $\hsd$ preserving the principal gradation, where $\hsd$ is the central extension of the Lie superalgebra of differential operators…
