Self-adjoint extensions of symmetric relations associated with systems of ordinary differential equations with distributional coefficients

Steven Redolfi, Rudi Weikard

We study the extension theory for the two-dimensional first-order system $J u^{'} + q u = w f$ of differential equations on the real interval $(a, b)$ where $J$ is a constant, invertible,…

On Fourier expansions for systems of ordinary differential equations with distributional coefficients

Steven Redolfi, Rudi Weikard

We study the spectral theory for the first-order system $J u^{'} + q u = w f$ of differential equations on the real interval $(a, b)$ where $J$ is a constant, invertible, skew-hermitian matri…
