Characterization of Self-Adjoint Extensions for Discrete Symplectic Systems
Journal of Mathematical Analysis and Applications (2016)
All self-adjoint extensions of minimal linear relation associated with the discrete symplectic system are characterized. Especially, for the scalar case ...
On Discrete Symplectic Systems: Associated Maximal and Minimal Linear Relations ...
Journal of Mathematical Analysis and Applications (2015)

On Weyl-Titchmarsh Theory for Singular Finite Difference Hamiltonian Systems
Journal of Computational and Applied Mathematics (2004)
We develop the basic theory of matrix-valued Weyl-Titchmarsh M-functions and the associated Green's matrices for whole-line and half-line self-adjoint Hamiltonian ...
On Povzner-Wienholtz-Type Self-Adjointness Results for Matrix-Valued Sturm - Liouville Operators
Proceedings of the Royal Society of Edinburgh Section A: Mathematics (2003)
We derive Povzner-Wienholtz-type self-adjointness results for m x m matrix-valued Sturm-Liouville operators T = R-1[- d/dx P d/dx + Q] ...
