It is well-known t hat solutions converge (in the limit of scale separation) to those of a de terministic equation\, a kind of law of large numbers result called 'homog enization'. In recent years obtaining quantitative information about this convergence has attracted a lot of attention\, which lead to the developme nt of new tools from analysis and probability. I will give an overview of one such approach to the topic based on variational methods\, elliptic reg ularity\, and ``renormalization-group'' arguments. \n\n \n DTSTART:20180319T200000Z DTEND:20180319T210000Z LOCATION:Room 920\, Burnside Hall\, CA\, QC\, Montreal\, H3A 0B9\, 805 rue Sherbrooke Ouest SUMMARY:Scott Armstrong (Courant Institute of Mathematical Sciences (NYU)) URL:/mathstat/channels/event/scott-armstrong-courant-i nstitute-mathematical-sciences-nyu-285754 END:VEVENT END:VCALENDAR
