The Cofinality of Cardinal Invariants Related to Measure and Category

Abstract

We prove that the following are consistent with ZFC. 1. $2^\omega = \aleph_{\omega_1} + K_C = \aleph_{\omega_1} + K_B = K_U = \omega_2$ (for measure and category simultaneously). 2. $2^\omega = \aleph_{\omega_1} = K_C(\mathscr{L}) + K_C(\mathscr{M}) = \omega_2$. This concludes the discussion about the cofinality of $K_C$.
