We consider a function f of Nevanlinna class such that its radial limit f(*
) is square summable on the unit circle T. We give a growth condition on th
e Taylor coefficients of f and the rate of decrease of the negatively index
ed Fourier coefficients of f(*) in order that f must belong to the Hardy cl
ass H-2 (C). C 2001 Academie des sciences/Editions scientifiques et medical
