Abstract

For a positive integer mm and a finite non-negative Borel measure μ\mu on the unit circle, we study the Hadamard multipliers of higher order weighted Dirichlet-type spaces Hμ,m\mathcal H_{\mu, m}. We show that if α>12,\alpha>\frac{1}{2}, then for any ff in Hμ,m,\mathcal H_{\mu, m}, the sequence of generalized Ces{\`a}ro sums {σnα[f]}\{\sigma_n^{\alpha}[f]\} converges to ff. We further show that if α=12\alpha=\frac{1}{2} then for the Dirac delta measure supported at any point on the unit circle, the previous statement breaks down for every positive integer mm.
