Abstract :
In our previous paper (Eda et al., to appear), we introduced a cardinal invariant b* and studied some properties of the cardinal b*. In the present paper we define new cardinal invariants which are related to Cichofiʹs diagram and generalize the notion of b*. We investigate the relations between them and other cardinals which appear in Cichońʹs diagram.
