In the paper one obtains the description of invariant subspaces of the multiplication operator
in the Hardy-Smirnov space Ep (G), where G is afinitely connected domain with a piecewise C2-smooth boundary. For the case of an analytic “interior boundary” Γint of the domain G and p=2, a more precise description is given, generalizing the Hitt—Sarason result on the invariant subspaces of the space H2 in a circular annulus.
