On the classical Reinforcement problem and Optimisation
arXiv:2602.17331 · doi:10.1016/j.na.2026.114180
Abstract
In the present survey, we consider the classical reinforcement problem for elliptic boundary value problems originally studied by Sanchez-Palencia in 1969. We focus on the seminar papers by Brezis, Caffarelli, & Friedman, and by Acerbi & Buttazzo, and discuss the related optimisation problems proposed by Friedman and by Buttazzo.
