We review recent results regarding the problem of the stability of Sobolev inequalities on Riemannian manifolds with Ricci curvature lower bounds. We shall describe techniques and methods from smooth and non-smooth geometry, the fruitful combination of which revealed particularly effective. Furthermore, we present a self-contained overview of the proof of the stability of the Sobolev inequality on manifolds with non-negative Ricci curvature and Euclidean volume growth, adopting a direct strategy tailored to this setting. Finally, we discuss related stability results and present some open problems.

Mosco-convergence of Cheeger energies on varying spaces satisfying curvature dimension conditions

Cheeger p-energies and BV total variations are lower-semicontinuous along pointed-measure Gromov–Hausdorff limits of essentially non-branching CD(K,N) and MCP(K,N) spaces, with a 2^N factor in the MCP case.
