We show that cardinal invariant ... introduced in [42] is their common critical cardinality and we study this combinatorial characteristic in its own. For instance, we show that ... and consequently if cov ... and J has the Baire property then ... Moreover, we show that control sequence ... in the definition of (I,sJ)wQN-space in [6] is not essential.
