  • We introduce a large family of reproducing kernel Hilbert spaces H⊂Hol(D), which include the classical Dirichlet-type spaces Dalfa, by requiring normalized monomials to form a Riesz basis for H. Then, after precisely evaluating the nth optimal norm and the n-th approximant of f(z)=1−z, we completely characterize the cyclicity of functions in Hol(D¯¯¯¯) with respect to the forward shift.
