N2 - We study properties of the embedding operators of model sub-spaces K Δp(defined by inner functions) in the Hardy space Hp(coinvariant subspaces of the shift operator). We find acriterion for the embedding of KΔP in Lp(μ) to be compact similar to the Volberg-Treil theorem on bounded embeddings, and give apositive answer to aquestion of Cima and Matheson. The proof is based on Bernstein-type inequalities for functions in KΔP. We investigate measures such that the embedding operator belongs to some Schatten-vonNeumann ideal.
