On discrete symplectic systems: Associated maximal and minimal linear relations and nonhomogeneous problems
Stephen Clark, Petr Zemánek
In this paper we characterize the definiteness of the discrete symplectic system, study a nonhomogeneous discrete symplectic system, and introduce the minimal and maximal linear re…

Characterization of self-adjoint extensions for discrete symplectic systems
Petr Zemánek, Stephen Clark
All self-adjoint extensions of minimal linear relation associated with the discrete symplectic system are characterized. Especially, for the scalar case on a finite discrete interv…
