On Dirichlet Spaces With a Class of Superharmonic Weights

Abstract: Abstract. In this paper, we investigate Dirichlet spaces D µ with superharmonic weights induced by positive Borel measures µ on the open unit disk. We establish the AlexanderTaylor-Ullman inequality for D µ spaces and we characterize the cases where equality occurs. We de ne a class of weighted Hardy spaces H µ via the balayage of the measure µ. We show that D µ is equal to H µ if and only if µ is a Carleson measure for D µ . As an application, we obtain the reproducing kernel of D µ when µ is an in nite sum o… Show more

“…We are going to show that the assumption σ < 2 in the proposition above is best possible. In other words, when σ ≥ 2, we can construct a counterexample of µ such that the induced weight function ω σ does not satisfy condition (3). Thus our condition (3) is sensitive enough to detect the changing behaviour of ω σ at the critical point σ = 2.…”

“…This double integral characterization was also used to study Hankel type operators; see [12,Section 4]. We refer to [6,Section 4] and [29] for some recent results associated with double integral estimates for some analytic function spaces. See A. Reijonen [26] for recent results on Besov type spaces induced by some radial weights.…”
