非全纯曲面丛与Lefschetz纤维化

Non-holomorphic surface bundles and Lefschetz fibrations

R. Inanc Baykur

摘要:

我们证明了某些稳定化如何产生无穷多个闭的定向4-流形,这些流形是亏格g曲面丛的全空间。Lefschetz纤维化)在亏格h曲面上,并且具有非零特征,但不允许具有任何一个方向的复结构,对于“大多数”(分别为所有)可能的值,g至少为3,h至少为2(分别地,g至少为2,h非负)。

英文摘要:

We show how certain stabilizations produce infinitely many closed oriented 4-manifolds which are the total spaces of genus g surface bundles (resp. Lefschetz fibrations) over genus h surfaces and have non-zero signature, but do not admit complex structures with either orientations, for "most" (resp. all) possible values of g at least 3 and h at least 2 (resp. g at least 2 and h non-negative).
