拉格朗日环面纤维化讲座

Lectures on Lagrangian torus fibrations

Jonathan David Evans

摘要:

这是一本针对辛几何研究生和研究人员的书,基于我在2019年教授的一门课程。主要的信息是拉格朗日环面纤维化的基础继承了一个积分仿射结构,你可以用它来“读出”全空间的许多有趣的几何形状。涵盖的主题包括:作用角坐标,辛减少,复曲面流形,可见和热带拉格朗日,几乎复曲面系统,Milnor纤维的循环商奇点,突变的多边形,非复曲面爆破,几乎复曲面的看法Lisca的分类填充的透镜空间,决议的尖点奇点,马尔可夫三元组和Vianna托里。这本书以一个简短的未决问题清单结束。在整个过程中,都强调例子,并有一些练习与解决方案。

英文摘要:

This is a book aimed at graduate students and researchers in symplectic geometry, based on a course I taught in 2019. The primary message is that the base of a Lagrangian torus fibration inherits an integral affine structure, which you can use to "read off" a lot of interesting geometry of the total space. Topics covered include: action-angle coordinates, symplectic reduction, toric manifolds, visible and tropical Lagrangians, almost toric systems, Milnor fibres of cyclic quotient singularities, mutation of polygons, non-toric blow-up, an almost toric view on Lisca's classification of fillings of lens spaces, resolutions of cusp singularities, Markov triples and Vianna tori. The book ends with a short list of open problems. Throughout there is an emphasis on examples and there are some exercises with solutions.
