### Changing cardinal characteristics without changing $\omega$--sequences or cofinalities

by Mildenberger and Shelah. [MdSh:684]

Annals Pure and Applied Logic, 2000

We show: There are pairs of universes V_1 subseteq V_2
and there is a notion of forcing P in V_1 such that the
change mentioned in the title occurs when going from V_1[G]
to V_2[G] for a P --generic filter G over V_2 . We use forcing
iterations with partial memories. Moreover, we implement highly
transitive automorphism groups into the forcing orders.
