Title: Preserving sequences of stationary subsets of omega_1

Abstract:

Let M be an inner model that computes omega_1 correctly. We show two results (due to Stevo Todorcevic and Paul Larson) on whether there is in M a partition of omega_1 into infinitely many sets that are stationary from the point of view of V.
