Some revisited results about composition operators on Hardy spaces
On the one hand, we generalize some results known for composition operators on Hardy spaces to the case of Hardy–Orlicz spaces H^\Psi : construction of a “slow” Blaschke product giving a non-compact composition operator on H^\Psi and yet “nowhere differentiable”; construction of a surjective symbol whose associated composition operator is …
