{wiki=Sarason_interpolation_theorem}
The Sarason interpolation theorem is a result in complex analysis related to the theory of functional spaces, particularly in the context of the Hardy space \\( H^2 \\). It provides a criterion for the existence of an analytic function that interpolates a given sequence of points in the unit disk, subject to certain conditions.
