明星手术与理性排污的比较

Comparing star surgery to rational blow-down

Laura Starkston

摘要:

我们比较了[KS]中介绍的星形手术操作和广义理性的排污。我们表明,明星手术的股票的属性,使合理的吹有用的小奇异辛4流形的建设。然后,我们表明,明星手术操作提供了一个严格的更一般的类的操作,证明有一个无限的家庭的明星手术是不等价于任何序列的广义辛合理的打击。这回答了Ozbagci向作者提出的一个问题。还证明了来自星外科手术操作的单值替换产生平面映射类幺半群中的关系,这些关系不能由[EMVHM 11]中确定的来自广义有理blowdown的关系正生成。

英文摘要:

We compare the star surgery operations introduced in [KS] to the generalized rational blow-down. We show that star surgery shares the properties that make rational blow-down useful for constructions of small exotic symplectic 4-manifolds. Then we show that star surgery operations provide a strictly more general class of operations by proving that there is an infinite family of star surgeries which are inequivalent to any sequence of generalized symplectic rational blow-downs. This answers a question posed to the author by Ozbagci. It also demonstrates that the monodromy substitutions coming from star surgery operations yield relations in planar mapping class monoids which cannot be positively generated by the relations determined in [EMVHM11] which come from the generalized rational blow-downs.
