New reals: Can live with them, can live without them
Mathematical Logic Quarterly 52 (2):115-124 (2006)
Abstract
We give a self-contained proof of the preservation theorem for proper countable support iterations known as “tools-preservation”, “Case A” or “first preservation theorem” in the literature. We do not assume that the forcings add realsOther Versions
