Abstract:  We explore the distinctions between $L^p$ convergence of metric tensors on a fixed Riemannian manifold vs. GH, uniform, and intrinsic flat convergence of the the resulting sequence of metric spaces. We provide a number of examples which demonstrate these notions of convergence do not agree even for two dimensional warped product manifolds with warping functions converging in the $L^p$ sense. We then prove a theorem which requires $L^p$ bounds from above and $C^0$ bounds from below on the warping functions to obtain enough control for the limits to agree.
