In continuation of [20], we analyze the properties of spectral minimal k-partitions of an open set Ω in ℝ3 which are nodal, i.e. produced by the nodal domains of an eigenfunction of the Dirichlet Laplacian in Ω . We show that such a partition is necessarily a nodal partition associated with a k-th eigenfunction. Hence we have in this case equality in Courant's nodal theorem.

Abstract

In continuation of [20], we analyze the properties of spectral minimal k-partitions of an open set Ω in ℝ3 which are nodal, i.e. produced by the nodal domains of an eigenfunction of the Dirichlet Laplacian in Ω . We show that such a partition is necessarily a nodal partition associated with a k-th eigenfunction. Hence we have in this case equality in Courant's nodal theorem.
