We consider approximation of L p functions by Hardy functions on subsets of the circle for \(1 \leq p < \infty\) . After some preliminaries on the possibility of such an approximation which are connected to recovery problems of the Carleman type, we prove existence and uniqueness of the solution to a generalized extremal problem involving norm constraints on the complementary subset.
