Cellularity,A BA . is said to satisfy the κ-. (κ-cc) if every disjoint subset of . has power <κ. Thus for κ non-limit, this is the same as saying that the cellularity of . is <κ. Of most interest is the ω.-chain condition, called ccc for short (countable chain condition). We shall return to it below.
