量子化乘法簇

Quantized multiplicative quiver varieties

David Jordan

摘要:

本文从一个代数Q的数据出发,利用它的维数向量d构造了一个代数D_q=D_q(Mat_d(Q)),它是仿射空间Mat_d(Q)上的微分算子代数的平坦q-变形.代数D_q对于量子一般线性群的乘积的作用是等变的,量子线性群在每个顶点上通过共轭作用。我们为这个作用量构造了一个量子矩映射,然后定义了D_q的哈密顿约化A^lambda_d(Q),其中矩参数为λ.我们证明了A^λ_d(Q)是Lusztig簇及其乘法对应簇的平坦形式变形,对于所有满足Crawley-Boevey平坦条件的维数向量:的确,A^λ_d(Q)上的乘积产生乘法簇上辛结构的Fedosov量子化。作为应用,我们给出了A_{n-1}型球面双仿射Hecke代数的表示范畴,以及Etingof,Oblomkov,和Rains构造的它的推广,用等变D_q-模范畴与非球面模的Serre子范畴的商表示.

英文摘要:

Beginning with the data of a quiver Q, and its dimension vector d, we construct an algebra D_q=D_q(Mat_d(Q)), which is a flat q-deformation of the algebra of differential operators on the affine space Mat_d(Q). The algebra D_q is equivariant for an action by a product of quantum general linear groups, acting by conjugation at each vertex. We construct a quantum moment map for this action, and subsequently define the Hamiltonian reduction A^lambda_d(Q) of D_q with moment parameter λ. We show that A^λ_d(Q) is a flat formal deformation of Lusztig's quiver varieties, and their multiplicative counterparts, for all dimension vectors satisfying a flatness condition of Crawley-Boevey: indeed the product on A^λ_d(Q) yields a Fedosov quantization the of symplectic structure on multiplicative quiver varieties. As an application, we give a description of the category of representations of the spherical double affine Hecke algebra of type A_{n-1}, and its generalization constructed by Etingof, Oblomkov, and Rains, in terms of a quotient of the category of equivariant D_q-modules by a Serre sub-category of aspherical modules.
