Covering of the null ideal may have countable cofinality
Fundamenta Mathematicae, Tome 166 (2000) no. 1, pp. 109-136
We prove that it is consistent that the covering number of the ideal of measure zero sets has countable cofinality.
Keywords:
null sets, cardinal invariants of the continuum, iterated forcing, ccc forcing
