In the case of $d=2$, a Dickman limit was proved in \\cite{PW04}. This raises the question, what happens in dimensions three and higher and is it possible to prove a quantitative limit theorem? In this paper, we prove a Gaussian central limit theorem for $d \\ge 3$. Moreover, by utilizing recent results from \\cite{BM21} originating in Stein's method, we provide presumably optimal non-asymptotic bounds on the Wasserstein and the Kolmogorov distances between the distributions of total length of rooted edges, suitably normalized, and a standard Gaussian random variable.", "revisions": [ { "version": "v1", "updated": "2021-05-01T18:27:50.000Z" } ], "analyses": { "subjects": [ "60F05", "60D05" ], "keywords": [ "random minimal directed spanning tree", "gaussian approximation", "gaussian central limit theorem", "total length", "presumably optimal non-asymptotic bounds" ], "note": { "typesetting": "TeX", "pages": 24, "language": "en", "license": "arXiv", "status": "editable" } } }
