Completeness of elementary solutions of second order elliptic equations in a semi-infinite tube domain
Boundary-value problems for second order abstract differential equations on a semi-axis are considered in this article. We find isomorphisms for the corresponding operators and prove completeness of elementary solutions corresponding to subsets of eigenvalues. As an application of the abstract resul...
