## Meeting

• Basically I want to apply central limit theorem for stationary processes (accounts for covariances), assuming mean zero

$\frac{X_1 + ... + X_n}{\sqrt{\sigma^2 n}} \propto N(0,1)$

where

$\sigma^2 = E X^2 + 2 \sum_{i,j}^n Cov(X_i, X_j)$

• Discussion of Freidlin–Wentzell theory in connection to Arrhenius law and the well-defined stochastic tipping point which occurs before the branch point.
• Kurtz results don't really help in the case of ergodicity, can make statements about the (even non-stationary) ensemble limit.
