But they would be artificial, but if you had a concrete system of that type in front of you, you should expect the behaviour you’re talking about. You would still have to work hard to prove it. | |
Apr 14, 2019 at 13:25 | comment | added | jason | @Anthony Quas Thanks for the example. But with the same setting of your example, assume decay rate of all $T_1$ is $e^{-n}$ , decay rate of all $T_0$ is $e^{-\sqrt{n}}$. Then the decay rate of any mix of $T_0$ and $T_1$ should be lying between them, and less than $e^{-\sqrt{n}}$. Can I deduce the decay rate of any mix of $T_0$ and $T_1$ is less than $e^{-\sqrt{n}}$ without $C_{\omega}$? | |
Apr 13, 2019 at 19:34 | comment | added | Anthony Quas | The $C_\omega$ is completely natural. You should imagine that you are applying two dynamical systems:$T_0$ and $T_1$ (so $\omega$ is a sequence of 0’s and 1’s). Imagine $T_1$ mixes much faster than $T_0$. Now if $\omega$ has a large number of initial 0’s, the mixing will be slow, so $C_\omega$ should be large. You would expect $C$ not to depend on $\onega$ if all of the fiber maps mix at the same rate. | |

A typo in the title is corrected.
