Moderate deviations for diffusions with Brownian potentials
Yueyun Hu, Zhan Shi
We present precise moderate deviation probabilities, in both quenched and annealed settings, for a recurrent diffusion process with a Brownian potential. Our method relies on fine…
On the increments of the principal value of Brownian local time
Endre Csáki, Yueyun Hu
Let be a one-dimensional Brownian motion starting from 0. Define $Y(t)= \int_0^t{\d s \over W(s)} := \lim_{ε\to0} \int_0^t 1_{(|W(s)|> ε)} {\d s \over W(s)} $ as Cauchy's princ…
Strong disorder for a certain class of directed polymers in a random environment
Philippe Carmona, Francesco Guerra, Yueyun Hu +1
We study a model of directed polymers with an exponentially recurrent Markov chain and an indefinitely divisible random environment. We prove that the normalized partition function…
Universality In Sherrington-Kirkpatrick's Spin Glass Model
Philippe Carmona, Yueyun Hu
We show that the limiting free energy in Sherrington-Kirkpatrick's Spin Glass Model does not depend on the environment.
