Cardinal invariants above the continuum
Abstract
We prove some consistency results about b(lambda) and d(lambda), which are natural generalisations of the cardinal invariants of the continuum b and d. We also define invariants bcl(lambda) and dcl(lambda), and prove that almost always b(lambda) = bcl(lambda) and d(lambda)=dcl(lambda)
