Splitted weight and index of divisibility in topological products / A. N. Yakivchik. // Vestnik Moskovskogo Universiteta. Seriya 1. Matematika. Mekhanika. 2012. № 3. P. 13-18 [Moscow Univ. Math. Bulletin. Vol. 72, N 2, 2017. P. 0].

The properties of splittability and divisibility introduced by A. V. Arhangel'skii and cardinal functions defined on their basis are considered. The growth of split weight and of divisibility degree when taking topological products is examined.

Key words: topological product, splittable space, divisibility degree, pseudoweight, i-weight, strict τ-discreteness.
