Abstract

The paper deals with the existence of solutions for singular higher order differential equations with Sturm–Liouville or (𝑝, 𝑛 – 𝑝) right focal boundary conditions or the (𝑛 – 𝑝, 𝑝) left focal boundary conditions. Right-hand sides of differential equations may be singular in the zero values of all their phase variables. The proofs are based on the regularization and sequential techniques.
