Abstract

We deal here with colorings of the pair (μ⁺, μ), when μ is a strong limit and singular cardinal. We show that there exists a coloring c with no refinement. It follows that the properties of colorings of (μ⁺, μ) when μ is singular differ in an essential way from the case of regular μ (although the identities may be the same).
