On Eigenfunctions of the Boundary Value Problems for Second Order Differential Equations with Involution
We give a definition of Green’s function of the general boundary value problems for non-self-adjoint second order differential equation with involution. The sufficient conditions for the basis property of system of eigenfunctions are established in the terms of the boundary conditions. Uniform equic...
