SMALL UNIVERSAL FAMILIES OF GRAPHS ON ℵω + 1
Published online by Cambridge University Press: 29 June 2016
Abstract
We prove that it is consistent that $\aleph _\omega $ is strong limit, $2^{\aleph _\omega } $ is large and the universality number for graphs on $\aleph _{\omega + 1} $ is small. The proof uses Prikry forcing with interleaved collapsing.
