The classical embedding theorem of Carleson deals with finite positive Borel measures μ on the closed unit disk for which there exists a positive constant c such that ‖f‖L2(μ) ≤ c‖f‖H2 for all f ∈ H, the Hardy space of the unit disk. Lefèvre et al. examined measures μ for which there exists a positive constant c such that ‖f‖L2(μ) ≥ c‖f‖H2 for all f ∈ H. The first type of inequality above was e...
