    dct:description """
              We prove a revised version of Laver's indestructibility theorem which slightly improves over the classical result. An application yields the consistency of $(\\kappa^+,\\kappa)\\notcc(\\aleph_1,\\aleph_0)$ when $\\kappa$ is supercompact. The actual proofs show that $\\omega_1$-regressive Kurepa-trees are consistent above a supercompact cardinal even though ${\\rm MM}$ destroys them on all regular cardinals. This rather paradoxical fact contradicts the common intuition.
