Identity crises between supercompactness and Vopenka's Principle
Abstract
In this paper we study the notion of C(n)-supercompactness introduced by Bagaria in Bag and prove the identity crises phenomenon for such class. Specifically, we show that consistently the least supercompact is strictly below the least C(1)-supercompact but also that the least supercompact is C(1)-supercompact (and even C(n)-supercompact). Furthermore, we prove under suitable hypothesis that the ultimate identity crises is also possible. These results solve several questions posed by Bagaria and Tsaprounis.
