Sažetak
In this paper, we study $q$-Sturm-Liouville operators. We construct
a space of boundary values of the minimal operator and describe all
maximal dissipative, maximal accretive, self-adjoint and other
extensions of $q$-Sturm-Liouville operators in terms of boundary
conditions. Then we prove a theorem on completeness of the system
of eigenfunctions and associated functions of dissipative operators
by using the Lidskii's theorem.
