Uniform upper bounds on Courant sharp Neumann eigenvalues of chain domains

Thomas Beck, Yaiza Canzani, Jeremy L. Marzuola

We obtain upper bounds on the number of nodal domains of Laplace eigenfunctions on chain domains with Neumann boundary conditions. The chain domains consist of a family of planar d…
