Liu, Chuan On weakly bisequential spaces. (English) Zbl 1038.54004 Commentat. Math. Univ. Carol. 41, No. 3, 611-617 (2000). Bisequential spaces were introduced by A.V.Arhangel’skii [Trans. Mosc. Math. Soc. 55, 207–219 (1994; Zbl 0842.54004)]. Some typical results from the reviewed paper: (2.1) Weakly bisequential spaces coincide with weakly bi-quotient images of metrizable spaces. (2.4) There are two compact weakly bisequential spaces the product of which is not Fréchet-Urysohn. (2.6) A Fréchet-Urysohn weakly quasi-first countable space is weakly bisequential. (2.7) A space is weakly bisequential if it is weakly quasi-first countable and \(\alpha _4\).
