We present generalizations to Krein spaces of the abstract interpolation and smoothing problems proposed by Atteia in Hilbert spaces: given a Krein space K and Hilbert spaces H and epsilon (bounded) surjective operators T : H -> K and V : H - epsilon, rho > 0 and a fixed z(0) is an element of epsilon, we study the
