A Large Deviation Principle for the Stochastic Heat Equation with General Rough Noise

نویسندگان

چکیده

We study the Freidlin–Wentzell large deviation principle for nonlinear one-dimensional stochastic heat equation driven by a Gaussian noise: $$\begin{aligned} \frac{\partial u^{{\varepsilon }}(t,x)}{\partial t}=\frac{\partial ^2 x^2}+\sqrt{{\varepsilon }}\sigma (t, x, }}(t,x))\dot{W}(t,x),\quad t> 0,\, x\in \mathbb {R}, \end{aligned}$$ where $$\dot{W}$$ is white in time and fractional space with Hurst parameter $$H\in \left( \frac{1}{4},\frac{1}{2}\right) $$ . Recently, Hu Wang (Ann Inst Henri Poincaré Probab Stat 58(1):379–423, 2022) have studied well-posedness of this without technical condition $$\sigma (0)=0$$ which was previously assumed et al. 45(6):4561–4616, 2017). adopt new sufficient proposed Matoussi (Appl Math Optim 83(2):849–879, 2021) weak convergence criterion principle.

Large Deviation Principle for General Occupancy Models

We use process level large deviation analysis to obtain the rate function for a general family of occupancy problems. Our interest is the asymptotics of the empirical distributions of various quantities (such as the fraction of urns that contain a given number of balls). In the general setting, balls are allowed to land in a given urn depending on the urn’s contents prior to the throw. We discu...

Stochastic Sub - Additivity Approach to the Conditional Large Deviation Principle

University of Chicago Given two Polish spaces AX and AY, let ρ AX × AY → d be a bounded measurable function. Let X = Xn n ≥ 1 and Y = Yn n ≥ 1 be two independent stationary processes on AX and A ∞ Y , respectively. The article studies the large deviation principle (LDP) for n−1 ∑n k=1 ρ Xk Yk , conditional on X. Based on a stochastic version of approximate subadditivity, it is shown that if Y s...

A large deviation principle with queueing applications

In this paper, we present a large deviation principle for partial sums processes indexed by the half line, which is particularly suited to queueing applications. The large deviation principle is established in a topology that is finer than the topology of uniform convergence on compacts and in which the queueing map is continuous. Consequently, a large deviation principle for steady-state queue...

A large deviation principle for Dirichlet posteriors

Let Xk be a sequence of independent and identically distributed random variables taking values in a compact metric space Ω, and consider the problem of estimating the law of X1 in a Bayesian framework. A conjugate family of priors for non-parametric Bayesian inference is the Dirichlet process priors popularized by Ferguson. We prove that if the prior distribution is Dirichlet, then the sequence...
