An equiconsistency for universal indestructibility
We obtain an equiconsistency for a weak form of universal indestructibility for strongness. The equiconsistency is relative to a cardinal weaker in consistency strength than a Woodin cardinal, Stewart Baldwin’s notion of hyperstrong cardinal. We also briefly indicate how our methods are applicable to universal indestructibility for supercompactness and strong compactness. ∗ 2000 Mathematics Subject Classifications: 03E35, 03E45, 03E55. †
