Arthur Apter: Indestructible strong compactness but not supercompactness

Week 1, Tuesday June 16, 14:10-15:00

I will discuss the construction of a model containing a supercompact cardinal kappa whose strong compactness, but not supercompactness, is fully indestructible under kappa-directed closed forcing. This is joint work with Joel Hamkins and Grigor Sargsyan.
