摘要
该文考虑了一个具强阻尼的随机sine-Gordon方程.通过引入加权范数与对关于时间为一阶的发展方程对应的线性算子正性的分解,证明了由该方程生成的随机动力系统的随机紧吸引子的存在性.
A strongly damped stochastic sine-Gordon equation is considered. By introducing weight norm and splitting positivity of the linear operator in the corresponding evolution equation of the first order with respect to time, existence of a compact random attractor is shown for a stochastic dynamical system generated by strongly damped sine-Gordon equations with white noise
