Let C be the convergent sequence {1/n : n ϵ N} with its limit 0 in the real line with the usual metric. In this paper, we show that for a straight space X, X × C is straight if and only if X × K is straight for any compact metric space K. Furthermore, we show that for a straight space X, if X × C is straight, then X is precompact. Note that the notion of straightness depends on the metric on X. Indeed, since the real line R with the usual metric is not precompact, R×C is not straight. On the other hand, we show that the product space of an open interval and C is straight.Reconocimiento - No comercial - Sin obra derivada (by-nc-nd)Straight spacesConvergent sequencePrecompactUniformly continuousArtículo2017-06-1610.4995/agt.2007.1877Abierto1989-4147
