Abstract
The paper deals with the second boundary-value problem for a second-order differential-difference equation with variable coefficients on the interval \((0,d)\) as well as with the question of conditions on the right-hand side of the equation that ensure the smoothness of the generalized solutions of the boundary-value problem on the whole interval \((0,d)\) for \(d \notin \mathbb{N}\).
