 Periodic homogenisation for $\phi^4_2$

  要:We consider a periodic homogenisation problem for $\phi^4_2$ , a toy model that combines both renormalisation in singular SPDEs and homogenisation. In this case, we show that two different orders of the two limiting procedures yield the same limit, for both the dynamics and the invariant measure. Joint work in progress with Yilin Chen.
