Core-carrier conjecture for analytic weighted Bergman spaces

From papers

Let GGcolon (0,)(0,)(0,\infty)\to(0,\infty) be the function occurring in the measure structure defined by, let wL1(T)w\in\mathcal{L}^1(\mathbb{T}) be a non-negative weight, and let

0dlog(1/G(x))dx=\int_0^d \log(1/G(x))\,dx=\infty

for every d>0d>0. Write core(w)\operatorname{core}(w) for the core of ww, and let P2(μ)\mathcal{P}^2(\mu) be the space associated with a measure μ\mu of the form. Core-carrier conjecture. If P2(μ)\mathcal{P}^2(\mu) is a space of analytic functions on D\mathbb{D}, then core(w)\operatorname{core}(w) is a carrier for ww. This would give a sharp version of the irreducibility result for the spaces under consideration, replacing the exponential-decay hypothesis by the non-integrability of logG\log G; the source does not state whether the conjecture is resolved.
