自由群的SL(3,C)Character簇的极小仿射坐标

Minimal Affine Coordinates for SL(3,C) Character Varieties of Free Groups

Sean Lawton

摘要:

设X是秩为r的自由群的SL(3,C)表示的模.本文确定了X的坐标环的极小生成元。这立刻给出了模的显式全局坐标,并确定了模的最小仿射嵌入的维数。一路上,我们利用gl(3,C)矩阵的r-元组的模有关的结果。因此,我们还陈述了gl(n,C),sl(n,C)和SL(n,C)中元素的r-元组的模的坐标环之间的一般不变理论对应。

英文摘要:

Let X be the moduli of SL(3,C) representations of a rank r free group. In this paper we determine minimal generators of the coordinate ring of X. This at once gives explicit global coordinates for the moduli and determines the dimension of the moduli's minimal affine embedding. Along the way, we utilize results concerning the moduli of r-tuples of matrices in gl(3,C). Consequently, we also state general invariant theoretic correspondences between the coordinate rings of the moduli of r-tuples of elements in gl(n,C), sl(n,C), and SL(n,C).
