Moderate deviations for the Langevin equation with strong damping

Lingyan Cheng, Ruinan Li, Wei Liu

In this paper, we establish a moderate deviations principle for the Langevin dynamics with strong damping. The weak convergence approach plays an important role in the proof.

Exponential convergence in the Wasserstein metric $W_{1}$ for one dimensional diffusions

Lingyan Cheng, Ruinan Li, Liming Wu

In this paper, we find some general and efficient sufficient conditions for the exponential convergence $W_{1, d} (P_{t} (x, \cdot), P_{t} (y, \cdot)) \leq K e^{- δ t} d (x, y)$ for the semigroup $…

Centered Sobolev inequality and exponential convergence in $Φ$ -entropy

Lingyan Cheng, Liming Wu

In this short paper we find that the Sobolev inequality $\frac{1}{p - 2} [(\int f^{p} d μ)^{2/ p} - \int f^{2} d μ] \leq C \int ∣\nabla f ∣^{2} d μ$ ( $p \geq 0$ ) is equival…
