Abstract:
We show that for many pairs of infinite cardinals $\kappa > \mu ^+ > \mu$, $(\kappa ^{+}, \kappa )\twoheadrightarrow (\mu ^+, \mu )$ is consistent relative to the consistency of a supercompact cardinal. We also show that it is consistent, relative to a huge cardinal, that $(\kappa ^{+}, \kappa )\twoheadrightarrow (\mu ^+, \mu )$ for every successor cardinal $\kappa$ and every $\mu < \kappa$, answering a question of Foreman.References
