Title: Learning from Penrose limits of less understood gravity dual pairs

Abstract: The Penrose limit simplifies both sides of the AdS/CFT correspondence, the gravity background and the field theory (to a subset of operators), so it can be used as a tool to understand cases of holographic dual pairs that are less understood. After reviewing the method, I will apply it to cases in 4d: T-duals of AdS_5xS_5, 3d: GJV model (conformal), the MNa model and its T-dual (nonconformal), and 2d: I-branes and fibered D5-branes. I will show that we learn some things, but some are still not understood.
