Jun 26, 2022 at 14:12 | comment | added | Martin Hairer | Got you, I thought $\epsilon$ was just a superscript (as it is for $\mathbb{P}^\epsilon$ in the same expression), not an actual exponent... | |
Jun 26, 2022 at 13:18 | comment | added | Nate River | Well $X \approx \text{exp}(1/\varepsilon)$, so $X^\varepsilon \approx e$ right? | |
Jun 26, 2022 at 12:37 | comment | added | Martin Hairer | Right, but if $\epsilon \log X \approx 1$, then $X \approx \exp(1/\epsilon)$, not $e$. (And the absolute error might be huge.) | |

Jun 26, 2022 at 11:55 | comment | added | Nate River | Ah yes, I guess we’re both saying the same thing. I meant to consider $\varepsilon \log X$. | |
Jun 26, 2022 at 10:22 | comment | added | Martin Hairer | You have to take $Y=\epsilon \log X$ for that, don’t you? | |
Jun 26, 2022 at 9:39 | comment | added | Nate River | Hm what happens is that, taking $Y = \log X$, we get that $|\varepsilon Y - 1| \to 0$ in probability, and so $|X^\varepsilon - e| \to 0$ also in probability. Or did I misunderstand something? | |
Jun 26, 2022 at 9:37 | comment | added | Martin Hairer | You missed the epsilon in the definition of $Y_\epsilon$ when trying to apply the earlier result, didn’t you? | |
