Basisness and completeness of Fucik eigenfunctions for the Neumann Laplacian
Falko Baustian, Vladimir Bobkov
We investigate the basis properties of sequences of Fucik eigenfunctions of the one-dimensional Neumann Laplacian. We show that any such sequence is complete in and a Ri…

Basisness of Fucik eigenfunctions for the Dirichlet Laplacian
Falko Baustian, Vladimir Bobkov
We provide improved sufficient assumptions on sequences of Fucik eigenvalues of the one-dimensional Dirichlet Laplacian which guarantee that the corresponding Fucik eigenfunctions…

Basis properties of Fucik eigenfunctions
Falko Baustian, Vladimir Bobkov
We establish sufficient assumptions on sequences of Fucik eigenvalues of the one-dimensional Laplacian which guarantee that the corresponding Fucik eigenfunctions form a Riesz basi…
