Title: Composite media, almost touching disks and the maximum principle
Time & Venue: 2026年1月16日（星期五）16：00-17：00 & N913
Abstract: We consider the setting of two disks in a domain in R2 which are almost touching and have finite and positive conductivities, giving rise to a divergence form elliptic equation with discontinuous coefficients. We use the maximum principle to give a new proof of a gradient bound of Li-Vogelius. This is a joint work with Ben Weinkove.
