    Orderability of topological groups and biradial spaces (English)
    0 references
    The authors investigate orderability of topological groups which is, according to a result by \textit{F. Cammaroto} and the reviewer [Boll. Unione Mat. Ital., VII. Ser., B 7, No. 3, 607-629 (1993; Zbl 0793.54023)], related to biradial spaces introduced by the reviewer [Publ. Inst. Math., Nouv. Sér. 39(53), 173-177 (1986; Zbl 0612.54038)]. It is shown: (1) A topological group is orderable iff it is suborderable; (2) If \(X\) is a space, then \(X^\omega\) is biradial iff \(X\) is bisequential.
