Then, by generalizing a result of Motorov, we show that for every non-empty zero-dimensional space $X$ there exists a non-empty zero-dimensional space $Y$ such that $X\\times Y$ is h-homogeneous. Also, we simultaneously generalize results of Motorov and Terada by showing that if $X$ is a space such that the isolated points are dense then $X^\\kappa$ is h-homogeneous for every infinite cardinal $\\kappa$. Finally, we show that a question of Terada (whether $X^\\omega$ is h-homogeneous for every zero-dimensional first-countable $X$) is equivalent to a question of Motorov (whether such an infinite power is always divisible by 2) and give some partial answers.", "revisions": [ { "version": "v2", "updated": "2011-12-04T04:09:58.000Z" } ], "analyses": { "subjects": [ "54B10" ], "keywords": [ "non-empty zero-dimensional space", "h-homogeneity", "infinite cardinal", "infinite power", "partial answers" ], "note": { "typesetting": "TeX", "pages": 10, "language": "en", "license": "arXiv", "status": "editable", "adsabs": "2009arXiv0911.1023M" } } }
