Understanding Preservation Theorems, II

Abstract

This is an exposition of much of Sections VI.3 and XVIII.3 of "Proper and Improper Forcing", including preservations for "no random reals over V", "reals of V form a non-meager set", "every dense open set contains a dense open set in V", weak bounding, and weak $\omega^\omega$-bounding. The current version of part I covering Sections VI.1 and VI.2 is available from the author.
