On higher-order differential operators with a singularity inside the interval.
Differential equations with singularities inside the interval arise in different areas of mathematics and in applications. A wide class of differential equations with turning points can be reduced to the equations considered by the author. This paper is concerned with the non-selfadjoint boundary value problem for the studied differential equation with homogeneous boundary conditions.
