On the delta-strongly compact cardinal, part 1
Bagaria and Magidor introduced a weak version of strong compactness, δ-strong compactness, which characterizes some compactness properties successfully.
Besides, they also find that the least δ-strongly compact cardinal has odd properties. For example, the least δ-strongly compact cardinal may be singular, which separates δ-strong compactness from strong compactness.
In this series of talk, we will explore some basic properties of δ-strongly compact cardinals, and identity crisis phenomenon among δ-strongly compact cardinals for different δ.
This is joint work with Jiachen Yuan.
