An informal introduction to quantitative stochastic homogenization
Jean-Christophe Mourrat · Journal of Mathematical Physics · 2019
Divergence-form operators with random coefficients homogenize over large scales. Over the last decade, an intensive research effort focused on turning this asymptotic statement into quantitative estimates. The goal of this note is to review one approach for doing so based on the idea of renormalization. The discussion is highly informal, with pointers to mathematically precise statements.
