We establish uniform estimates for Green's functions associated to Kähler forms, as the latter evolve in large families and the complex structure varies. This generalizes works of Guo, Phong, Song, and Sturm. These estimates allow one to establish diameter bounds and non-collapsing estimates for various families of canonical Kähler metrics. This is joint work with T.D.Tô.

We establish improved Hardy inequalities for the magnetic p-Laplacian due to adding nontrivial magnetic fields. We also prove that for Aharonov-Bohm magnetic fields the sharp constant in the Hardy inequality becomes strictly larger than in the case of a magnetic-free p-Laplacian. We also post some remarks with open problems. This is based on a joint work with D. Krejčiřík N. Lam and A. Laptev.
