We will speak about joint work with Menachem Kojman and Dave Milovich on a class of topological cardinal invariants capturing base properties studied by the Russian school since the seventies. We will discuss analogies and differences between these cardinal invariants and the "cellularity" of a topological space, that is the supremum of the sizes of families of pairwise disjoint non-empty open sets. We will discuss their behavior in products and independence phenomena regarding their value on box products.
