ADE and affine ADE bundles over complex surfaces with pg = 0. / CUHK electronic theses & dissertations collection

January 2013 (has links)
我们研究了P[subscript g]=0 的复曲面x 上的ADE 向量丛和仿射ADE 向量丛。 / 首先,我们假设x 上有一个ADE 奇异点。这个奇异点在极小分解Y 中的例外轨迹是一条相应形式的ADE 曲线。利用这条ADE 曲线和向量丛的扩张,我们构造了Y 上的一个ADE 向量丛,而且这个向量丛可以下降到x上。此外,我们利用Y 上( -1)- 曲线的组合,描述了他们的极小表示向量丛。 / 其次,我们假设x 是一个椭圆曲面,而且x 上有一个仿射ADE 形式的奇异纤维。类似于以前,我们构造了X 上的一个仿射ADE 向量丛,而且这个向量丛在这条仿射ADE 曲线上的每一个不可约成分上都是平凡的。 / 然后,当X 是P²上突起n ≤9 个点时, x 上有一个典型的En 向量丛。我们详细的研究了x 的几何和这个E[subscript n] 向量丛的可变形性之间的关系。 / We study ADE and affine ADE bundles over complex surfaces X with P[subscript g] = 0. / First, we suppose X admits an ADE singularity. The exceptional locus of this singularity in the minimal resolution Y is an ADE curve of corresponding type. Using this ADE curve and bundle extensions, we construct an ADE bundle over Y which can descend to X. Furthermore, we describe their minuscule representation bundles in terms of configuration of (reducible) (-1)-curves. / Second, we assume X is an elliptic surface with a singular fiber of affine ADE type. Similar to above studies, we construct the affine ADE bundle over X which is trivial on each irreducible component of the affine ADE curve. / Third, when X is the blowup of P² at n ≤9 points, there is a canonical E[subscript n] bundle over it. We give a detailed study of the relationship between the geometry of X and the deformability of this bundle. / Detailed summary in vernacular field only. / Detailed summary in vernacular field only. / Detailed summary in vernacular field only. / Detailed summary in vernacular field only. / Chen, Yunxia. / On t.p.
