Where to place a spherical obstacle so as to maximize the second Dirichlet eigenvalue

Ahmad El Soufi, Rola Kiwan

We prove that among all doubly connected domains of bounded by two spheres of given radii, the second eigenvalue of the Dirichlet Laplacian achieves its maximum when…

Extremal first Dirichlet eigenvalue of doubly connected plane domains and dihedral symmetry

Ahmad El Soufi, Rola Kiwan

We deal with the following eigenvalue optimization problem: Given a bounded domain , how to place an obstacle of fixed shape within so as to maximize or mini…
