解析多频拟周期余圈的李雅普诺夫指数的连续性

Continuity of the Lyapunov exponent for analytic multi-frequency quasiperiodic cocycles

Matthew Powell

摘要:

已知解析单频拟周期余圈的李雅普诺夫指数在余圈内连续,当频率为无理数时,其李雅普诺夫指数在余圈和频率上联合连续。本文推广了Bourgain的一个结果,得到了多频拟周期$M(2,\mathbb{C})$余圈的连续性结果.我们的推论包括应用到多频Jacobi上循环周期性的背景电位。

英文摘要:

It is known that the Lyapunov exponent of analytic 1-frequency quasiperiodic cocycles is continuous in cocycle and, when the frequency is irrational, jointly in cocycle and frequency. In this paper, we extend a result of Bourgain to show the same continuity result for multifrequency quasiperiodic $M(2,\mathbb{C})$ cocycles. Our corollaries include applications to multifrequency Jacobi cocycles with periodic background potentials.
