Abstract:
We consider two-dimensional Schrödinger operators in bounded domains. Abstractions of nodal sets are introduced and spectral conditions for them ensuring that they are actually zero sets of eigenfunctions are given. This is illustrated by an application to optimal partitions.
Key words and phrases:
Schödinger operator, Nodal domain, Spectral theory.
