For an irreducible subset system H and $T_{0}$ spaces $X$ and $Y$, it is proved that $Y$ is H-sober iff the function space $\\mathbb{C}(X, Y)$ of all continuous functions $f : X\\longrightarrow Y$ equipped with the topology of pointwise convergence is H-sober iff the function space $\\mathbb{C}(X, Y)$ equipped with the Isbell topology is H-sober. One immediate corollary is that for a $T_{0}$ space $X$, $Y$ is a sober space (resp., $d$-space, well-filtered space) iff the function space $\\mathbb{C}(X, Y)$ equipped with the topology of pointwise convergence is a sober space (resp., $d$-space, well-filtered space) iff the function space $\\mathbb{C}(X, Y)$ equipped with the the Isbell topology is a sober space (resp., $d$-space, well-filtered space). It is shown that $T_{0}$ spaces $X$ and $Y$, if the function space $\\mathbb{C}(X, Y)$ equipped with the compact-open topology is H-sober, then $Y$ is H-sober. The function space $\\mathbb{C}(X, Y)$ equipped with the Scott topology is also discussed.", "revisions": [ { "version": "v1", "updated": "2022-04-19T07:09:04.000Z" } ], "analyses": { "subjects": [ "54C35", "54D99", "06B30", "06B35" ], "keywords": [ "function space", "h-sober spaces", "well-filtered space", "isbell topology", "pointwise convergence" ], "note": { "typesetting": "TeX", "pages": 11, "language": "en", "license": "arXiv", "status": "editable" } } }
