Abstract
We provide improved sufficient assumptions on sequences of Fucik eigenvaluesof the one-dimensional Dirichlet Laplacian which guarantee that the corresponding Fucik eigenfunctions form a Riesz basis in \(L^2(0,\pi)\) . For that purpose, we introduce a criterion for a sequence in a Hilbert space to be a Riesz basis.
