圆和零流形上斜积的Möbius不交性

Möbius disjointness for skew products on a circle and a nilmanifold

Wen Huang, Jianya Liu, Ke Wang

摘要:

设$\mathbb{T}$是单位圆,$Γ\backslash G$是$3$维海森堡流形.证明了$\mathbb{T} \times Γ\backslash G$上的一类斜积是远点的,并且默比乌斯函数与这些斜积是线性无缘的.这证明了Sarnak的莫比乌斯不相交猜想。

英文摘要:

Let $\mathbb{T}$ be the unit circle and $Γ\backslash G$ the $3$-dimensional Heisenberg nilmanifold. We prove that a class of skew products on $\mathbb{T} \times Γ\backslash G$ are distal, and that the Möbius function is linearly disjoint from these skew products. This verifies the Möbius Disjointness Conjecture of Sarnak.
