Anosov同构空间

The space of Anosov diffeomorphisms

F. Thomas Farrell, Andrey Gogolev

摘要:

本文考虑Anosov同构空间$\X$同伦于infranilmanifold $M$的固定自同构$L$.证明了若$M$是2-环面$\mathbb T^2$,则$\X$同伦等价于$\mathbb T^2$ .相反,如果$M$的维数足够大,我们证明了$\X$是丰富的同伦和有无穷多个连通分支。

英文摘要:

We consider the space $\X$ of Anosov diffeomorphisms homotopic to a fixed automorphism $L$ of an infranilmanifold $M$. We show that if $M$ is the 2-torus $\mathbb T^2$ then $\X$ is homotopy equivalent to $\mathbb T^2$. In contrast, if dimension of $M$ is large enough, we show that $\X$ is rich in homotopy and has infinitely many connected components.
