Eigenstructure of nonselfadjoint complex discrete vector Sturm-Liouville problems
Advances in Difference Equations volume 2005, Article number: 101430 (2005)
We present a study of complex discrete vector Sturm-Liouville problems, where coefficients of the difference equation are complex numbers and the strongly coupled boundary conditions are nonselfadjoint. Moreover, eigenstructure, orthogonality, and eigenfunctions expansion are studied. Finally, an example is given.
