We denote by $EM(X)$ the space consisting of admissible metrics on $X$, which can be extended to an admissible metric on $\\alpha X$, endowed with the compact-open topology. Let $ \\mathbf{c}_0 \\subset (0,1)^\\mathbb{N}$ be the space of sequences converging to $0$. In this paper, we shall show that if $X$ is separable, locally connected and locally compact but not compact, and there exists a sequence $\\{C_i\\}$ of connected sets in $X$ such that for all positive integers $i, j \\in \\mathbb{N}$ with $|i - j| \\leq 1$, $C_i \\cap C_j \\neq \\emptyset$, and for each compact set $K \\subset X$, there is a positive integer $i(K) \\in \\mathbb{N}$ such that for any $i \\geq i(K)$, $C_i \\subset X \\setminus K$, then $EM(X)$ is homeomorphic to $ \\mathbf{c}_0$.", "revisions": [ { "version": "v1", "updated": "2022-02-17T11:57:46.000Z" } ], "analyses": { "subjects": [ "54C35", "57N20", "54E35", "54E40", "54E45" ], "keywords": [ "locally compact metrizable spaces", "compact-open topology", "topological type", "spaces consisting", "positive integer" ], "note": { "typesetting": "TeX", "pages": 0, "language": "en", "license": "arXiv", "status": "editable" } } }
