Abstract: Harmonic functions in narrow regions with Neumann boundary conditions are used to model the electric potential in the presence of insulating inclusions a short distance apart. The gradient of the harmonic function - the electric field - may blow up as the inclusions approach each other. Optimal estimates for the electric field were recently obtained by Dong-Li-Yang. I will discuss a maximum principle approach to this problem, known as the insulated conductivity problem.
