Boundary conditions may include derivatives of the solution. A constructive criterion of continuous parameter dependence is obtained. On the finite inteval Sturm-Liouville differential expression with singular coefficients is considered. Corresponding operators are correctly defined as quasi-differential. The conditions for the minimal operator to be symmetric are found and its self-adjoint, maximal dissipative and maximal accumulative extensions are descrbed in terms of boundary conditions.
