| Dec 3, 2012 at 6:07 | comment | added | François G. Dorais | Preliminary thoughts on (1) and (2)... The answer to (1) ought to be yes but the way to get there is not necessarily the obvious one. For (2), Jensen's construction depends heavily on $\square_{\omega_1}$ in order to "iterate" Souslin trees for length $\omega_2$; I don't think it's known whether such additional devices are necessary. Also, Jensen's construction uses a preparatory step that preserves $\diamondsuit_{\omega_1}$ but kills $\diamondsuit_{\omega_1}^*$; it is an open problem whether that step is necessary. | |
