From the assumption of a measurable cardinal and a precipitous ideal on
omega one, I will construct a Namba-style forcing that preserves omega one
and increases delta one two. If the precipitous ideal is the nonstationary
ideal, then the forcing preserves stationary subsets of omega one. I plan
to include detailed proofs.
