。Chakiris[5]构造了亏格为2的具有分离奇异纤维的全纯Lefschetz纤维的例子,并在20世纪70年代末的S中证明了这类纤维的一个分类定理.我们从拓扑学上推广了他的部分构造,给出了具有分离奇异纤维的任意亏格的超椭圆Lefschetz纤维的新例子,其中包括同胚但非微分纯的4-流形.
. Chakiris [5] constructed examples of holomorphic Lefschetz fibra tions of genus 2 with separating singular fibers and proved a classifica tion theorem for such fibrations in the late 1970's. We generalize some parts of his construction topologically to give new examples of hyper elliptic Lefschetz fibrations of arbitrary genus with separating singular fibers which include homeomorphic but non-diffeomorphic 4-manifolds.
