An almost strong relation

Research output: Contribution to journalArticlepeer-review

Abstract

Let µ be a strong limit singular cardinal. We prove that if 2µ > µ+ then the almost strong polarized partition relation (µµ+) → (µτ)θ for every ordinal τ < µ+ and for every θ < cf(µ). We obtain an optimal positive relation under 2µ = µ+, as after collapsing 2µ to µ+ this positive relation is preserved.
