Two cardinal models for singular mu

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