By extending the techniques from the case of reflexive Bergman spaces we characterize the solid core of $A_\\mu^1$. Also, as a consequence of a characterization of solid $A_\\mu^1$-spaces we show that, in the case of entire functions, there indeed exist solid $A_\\mu^1$-spaces. The second part of the paper is restricted to the case of the unit disc and it contains a characterization of the solid hull of $A_\\mu^1$, when $\\mu $ equals the weighted Lebesgue measure with weight $v$. The results are based on a duality relation of weighted $A^1$- and $H^\\infty$-spaces, the validity of which requires the assumption that $- \\log v$ belongs to the class $\\mathcal{W}_0$, studied in a number of publications; moreover, $v$ has to satisfy condition $(b)$, introduced by the authors. The exponentially decreasing weight $v(z) = \\exp( -1 /(1-|z|)$ provides an example satisfying both assumptions.", "revisions": [ { "version": "v1", "updated": "2022-03-03T09:18:54.000Z" } ], "analyses": { "keywords": [ "weighted bergman spaces", "solid core", "unit disc", "entire functions", "non-atomic borel measures" ], "note": { "typesetting": "TeX", "pages": 0, "language": "en", "license": "arXiv", "status": "editable" } } }
