A space of boundary values is constructed for minimal symmetric regular and singular q-Sturm– Liouville operators in limit-point and limit-circle cases. A description of all maximal dissipative, maximal accumulative, self-adjoint, and other extensions of such symmetric q-Sturm–Liouville operators is given in terms of boundary conditions.
