"In this paper we discuss disconjugacy of symplectic difference systems in the relation with positive definiteness of a certain associated block tridiagonal matrix. Analogous results have been recently proven for a special form of a symplectic systems - linear Hamiltonian difference systems and Sturm-Liouville difference equations. Finally, reciprocal systems are also discussed."@cs . . . "1"^^ . . "18"^^ . "1"^^ . "US - Spojen\u00E9 st\u00E1ty americk\u00E9" .
