Abstract :
We prove that every composition operator C ϕ on the Bloch space (modulo constant functions) attains its norm and characterize the norm-attaining composition operators on the little Bloch space (modulo constant functions). We also identify the extremal functions for ‖ C ϕ ‖ in both cases.
