Geodesic LÃ©vy flights on Zoll surfaces

Yann Chaubet, Emanuel JÃ³zsef Godfried, Leo Tzou

We study the mean first capture time of isotropic LÃ©vy flights on Zoll surfaces, namely the expected time for a geodesic LÃ©vy process to reach a shrinking geodesic ball. While th…

Minimax spectral estimation of weighted Laplace operators

Yann Chaubet, Vincent Divol

Given $n$ i.i.d. observations, we study the problem of estimating the spectrum of weighted Laplace operators of the form $I^_{f} = I^ + I^\pm \nabla lo g f \cdot \nabla$ , where $f$ is a posi…

Combinatorial zeta functions counting triangles

In this paper, we compute special values of certain combinatorial zeta functions counting geodesic paths in the (n-1)-skeleton of a triangulation of a n-dimensional manifold. We sh…
