Abstract
In this paper, we characterize the possible cofinalities of the least -strongly compact cardinal. We show that, on the one hand, for any regular cardinal, , that carries a -complete uniform ultrafilter, it is consistent, relative to the existence of a supercompact cardinal above , that the least -strongly compact cardinal has cofinality . On the other hand, provably the cofinality of the least -strongly compact cardinal always carries a -complete uniform ultrafilter.
