Jul 21, 2013 at 4:13 | comment | added | Andreas Blass | Joel has completely answered the question, but I hope the following two remarks might be useful for St.D. or for other readers. (1) Contrary to the implicit assumption in the question, if $T\in U$, it need not follow that $X\in W$. As Joel showed, it does follow that some $q\leq p$ forces $X$ to be in $W$, but $G$ might happen not to contain such a $q$. (2) Since the notion of forcing $P$ has size $<\kappa$, you can assume, replacing it with an isomorphic copy, that it is in $V_\kappa$. That will simplify Joel's $j$ argument slightly as $j$ will fix $P$ and all its members. | |
