In the paper a new integral representation of the well-known function classes $\mathscr H_2[\alpha]$ ($0\alpha1$) is established, which in the limiting case $\alpha=1$ goes into the Paley–Wiener theorem. A Hilbert space metric is introduced into the classes $\mathscr H_2[\alpha]$ ($0\alpha+\infty$), and a criterion for closedness of certain systems of functions in these spaces is established. In particular, a theorem of Müntz–Szász type in the complex domain is proved, and a complete intrinsic description is given of the corresponding nonclosed systems. Bibliography: 9 titles.
