Abstract

The Lindelof degree and extent were studied in Buhagiar et al. (Cent Eur J Math 12(8):1249–1264, 2014) in relation to lexicographic products of linearly ordered spaces. In this paper we consider the behaviour of other important cardinal functions, such as spread, density, weight and character, in such lexicographic products. Namely, we study the relation between a particular cardinal function on a lexicographic product of linearly ordered spaces and that cardinal function on each factor of the product.
