李群的镜像对称、朗兰兹对偶和交换元

Mirror symmetry, Langlands duality, and commuting elements of Lie groups

Michael Thaddeus

摘要:

通过正规化约化李群G中交换元对的空间和相应的Langlands对偶群的空间,构造了满足Strominger-Yau-Zaslow意义下的镜像条件的超kahler轨道对.对于紧李群中的交换四元组也是如此。霍奇数的镜像合作伙伴,或更准确地说,他们的orbifold E-多项式,显示同意,如预测的镜像对称。当G是SL(n)的商时,这些多项式被显式地计算。

英文摘要:

By normalizing the space of commuting pairs of elements in a reductive Lie group G, and the corresponding space for the Langlands dual group, we construct pairs of hyperkahler orbifolds which satisfy the conditions to be mirror partners in the sense of Strominger-Yau-Zaslow. The same holds true for commuting quadruples in a compact Lie group. The Hodge numbers of the mirror partners, or more precisely their orbifold E-polynomials, are shown to agree, as predicted by mirror symmetry. These polynomials are explicitly calculated when G is a quotient of SL(n).
