杨-米尔斯理论与跳跃曲线

Yang Mills theory and jumping curves

Yasha Savelyev

摘要:

本文研究了全纯向量丛跳跃曲线的光滑模拟,并利用$ S ^{2} $上的Yang-Mills理论证明了光滑单连通流形上的任何非平凡的光滑Hermite向量丛$E $都必有这样的曲线.这是用来给新的例子复流形,其中一个非平凡的全纯向量丛必须有跳跃曲线在经典意义上,(当$c_1 (E)$是零)。我们还利用这一点给出了Gromov关于酉联络的曲率范数的一个定理的新证明,并使该定理更加尖锐。最后结合光滑跳跃曲线理论,定义了一系列新的光滑流形的非平凡整数不变量,并对这些不变量进行了计算。我们的方法包括应用最近开发的Morse-Bott链复形的杨米尔斯功能超过$S ^{2} $。

英文摘要:

We study a smooth analogue of jumping curves of a holomorphic vector bundle, and use Yang-Mills theory over $ S ^{2} $ to show that any non-trivial, smooth Hermitian vector bundle $E $ over a smooth simply connected manifold, must have such curves. This is used to give new examples complex manifolds for which a non-trivial holomorphic vector bundle must have jumping curves in the classical sense, (when $c_1 (E)$ is zero). We also use this to give a new proof a theorem of Gromov on the norm of curvature of unitary connections, and make the theorem slightly sharper. Lastly we define a sequence of new non-trivial integer invariants of smooth manifolds, connected to this theory of smooth jumping curves, and make some computations of these invariants. Our methods include an application of the recently developed Morse-Bott chain complex for the Yang-Mills functional over $S ^{2} $.
