Homogenisation for the Robin eigenvalue problem on manifolds and flexibility of optimal Schrödinger potentials
Chia-Chun Lo
We show that the spectrum of a Schrödinger eigenvalue problem posed on a closed Riemannian manifold with non-negative potential can be approached by that of Robin eigenvalue pr…

Diffusion enhancement and Taylor dispersion for rotationally symmetric flows in discs and pipes
Michele Coti Zelati, Michele Dolce, Chia-Chun Lo
In this note, we study the long-time dynamics of passive scalars driven by rotationally symmetric flows. We focus on identifying precise conditions on the velocity field in order t…
