• Abstract:
This note is intended as a supplement and clarification to the proof of Theorem 3.3 of [ShSr:465]; namely, it is consistent that {\mathfrak b}=\aleph_1 yet for every ultrafilter U on \omega there is a \leq^* chain \{f_\xi:\xi\in\omega_2\} such that \{f_\xi/U:\xi\in\omega_2\} is cofinal in \omega/U.
