Neumann domains of planar analytic eigenfunctions

T. V. Anoop, Vladimir Bobkov, Mrityunjoy Ghosh

Along with the partition of a planar bounded domain $\hat{I}\text{c◯}$ by the nodal set of a fixed eigenfunction of the Laplace operator in $\hat{I}\text{c◯}$, one can consider another natural partition of $Î…
