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.

This is joint work with Christina Sormani.
