On some properties of linearly Lindelöf spaces. (English) Zbl 0964.54018
Summary: Improving an earlier result in [the authors, Proc. Am. Math. Soc. 127, No. 8, 2449-2458 (1999; Zbl 0930.54003)], we show that the cardinality of a sequential linearly Lindelöf Tikhonov space \(X\) does not exceed \(2^\omega\) if and only if the pseudocharacter of \(X\) does not exceed \(2^\omega\). We also establish that every locally metrizable linearly Lindelöf regular space is separable and metrizable.
