摘要翻译:
设X是秩r自由群的SL(3,C)表示的模。本文确定了X的坐标环的最小生成元,从而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。在这一过程中,我们利用了关于gl(3,C)中矩阵的r-元组的模的结果。因此,我们还证明了gl(n,C)、sl(n,C)和sl(n,C)中元素的r元组模的坐标环之间的一般不变理论对应关系。

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).
