When studying the geometry and topology of Riemannian manifolds with a lower Ricci curvature bound, it is natural and has proven useful to consider spaces that appear as limits of sequences of such manifolds, also called 'Ricci limit spaces'. These spaces do not need to be smooth, and analysing them has been an active research topic since the 1990s when they were introduced by Cheeger and Colding. An important role in their study is played by their 'tangent cones', which generalise the notion of a tangent space of a smooth manifold.
