摘要:
AbstractSymmetry‐ and selfadjointness‐conditions are derived for ordinary differential‐integral‐interface operators under integral‐interface conditions. Criteria for the existence of selfadjoint extensions inL n2×L n2are given. These extensions are characterized in a constructive way. The main tools are some extension‐theorems for linear relations (subspaces), wich are develo
