Spectral isoperimetric inequalities for Robin Laplacians on 2-manifolds and unbounded cones
Magda Khalile, Vladimir Lotoreichik
We consider the problem of geometric optimization of the lowest eigenvalue for the Laplacian on a compact, simply-connected two-dimensional manifold with boundary subject to an att…

Effective operators for Robin eigenvalues in domains with corners
Magda Khalile, Thomas Ourmières-Bonafos, Konstantin Pankrashkin
We study the eigenvalues of the Laplacian with a strong attractive Robin boundary condition in curvilinear polygons. It was known from previous works that the asymptotics of severa…
