I have convinced myself $F \cup G$ generates a unique ultrafilter just in case the condition you describe involving partitions of $\omega$ holds. I will update once I have carefully run the argument you suggested, to construct a positive answer to Q1 under CH. Again, the suggestion is much appreciated. | |
