零李雅普诺夫指数与Kontsevich-Zorich上循环的单值性

Zero Lyapunov exponents and monodromy of the Kontsevich-Zorich cocycle

Simion Filip

摘要:

我们描述了所有的情况下,Kontsevich-Zorich上循环有零李雅普诺夫指数。这是一个由Forni、Matheus和Zorich提出的猜想,只有当上循环满足额外的几何约束时才会发生。我们还描述了可以出现在单值的Kontsevich-Zorich上循环的实李群。零指数的数量则尽可能小,给定其单值性。

英文摘要:

We describe all the situations in which the Kontsevich-Zorich cocycle has zero Lyapunov exponents. Confirming a conjecture of Forni, Matheus, and Zorich, this only occurs when the cocycle satisfies additional geometric constraints. We also describe the real Lie groups which can appear in the monodromy of the Kontsevich-Zorich cocycle. The number of zero exponents is then as small as possible, given its monodromy.
