On the Cheeger inequality in Carnot-Carathéodory spaces
Martijn Kluitenberg
We generalize the Cheeger inequality, a lower bound on the first nontrivial eigenvalue of a Laplacian, to the case of geometric sub-Laplacians on rank-varying Carnot-Carathéodory s…

Chaotic light scattering around extremal black holes
Martijn Kluitenberg, Diederik Roest, Marcello Seri
We show that the scattering of light in the field of static extremal black holes is chaotic in the planar case. The relativistic dynamics of such extremal objects reduce…
