Cascading Variants of Internal Approachability
Hannes Jakob
Abstrak
We construct models in which there are stationarily many structures that exhibit different variants of internal approachability at different levels. This answers a question of Foreman. We also show that the approachability property at $μ$ is consistent with having a distinction of variants of internal approachability for stationarily many $N\in[H(μ^+)]^μ$. This is obtained using a new version of Mitchell Forcing.
