Probability 2022-11-29 v1

Abstract

This paper is devoted to investigating Freidlin-Wentzell's large deviation principle for one (spatial) dimensional nonlinear stochastic wave equation 2u\e(t,x)t2=2u\e(t,x)x2+\eσ(t,x,u\e(t,x))W˙(t,x)\frac{\partial^2 u^{\e}(t,x)}{\partial t^2}=\frac{\partial^2 u^{\e}(t,x)}{\partial x^2}+\sqrt{\e}\sigma(t, x, u^{\e}(t,x))\dot{W}(t,x), where W˙\dot{W} is white in time and fractional in space with Hurst parameter H(14,12)H\in(\frac 14,\frac 12). The variational framework and the modified weak convergence criterion proposed by Matoussi et al. \cite{MSZ} are adopted here.
