Onsager-Machlup functional for loop measures

Marco Carfagnini, Yilin Wang

We relate two ways to renormalize the Brownian loop measure on the Riemann sphere. One by considering the Brownian loop measure on the sphere minus a small disk, known as the norma…

Spectral gap bounds on H-type groups

Marco Carfagnini, Maria Gordina

In this note we provide bounds on the spectral gap for the Dirichlet sub-Laplacians on -type groups. We use probabilistic techniques and in particular small deviations of the co…
