generalized solutions to boundary value problems for neutral differential-difference equations on a finite interval (0, 𝑑) can be violated and preserved only on some subintervals.
However, for generalized eigenfunctions of differential-difference operators the problem of
smoothness remained open. In this lecture we obtain the necessary and sufficient conditions of smoothness for eigenfunctions of differential-difference operators. The talk will be
based on joint work with R. Yu. Vorotnikov.
