DESCRIPTION:Title: <a href="https://researchseminars.org/talk/SIAM-PDE/23/
 ">Coarse-graining\, renormalization\, and quantitative homogenization</a>\
 nby Scott Armstrong (Courant Institute/NYU\, United States) as part of Sem
 inar In the Analysis and Methods of PDE (SIAM PDE)\n\n\nAbstract\nI will p
 resent an overview of the theory of quantitative homogenization (stochasti
 c as well as periodic) for elliptic and parabolic equations\, which has be
 en developed in the last ten years. A particular emphasis will be on the i
 dea of "coarse-graining the coefficient field" with applications to degene
 rate equations and other situations which require "renormalization\," incl
 uding some more recent applications to models in mathematical physics. Tim
 e permitting\, I will discuss what I see as some of the most important ope
 n problems in the subfield.\n
