湍流随机壳模型的大偏差
Large Deviations for the Stochastic Shell Model of Turbulence
摘要:
本文首先证明了带有小乘性噪声的随机GOY湍流模型的强解的存在唯一性。然后利用弱收敛方法,在一定的Polish空间中建立了随机GOY模型解的Laplace原理。利用Varadhan和Bryc的某些结果,建立了Wentzell-Freidlin型大偏差原理。
英文摘要:
In this work we first prove the existence and uniqueness of a strong solution to stochastic GOY model of turbulence with a small multiplicative noise. Then using the weak convergence approach, Laplace principle for so- lutions of the stochastic GOY model is established in certain Polish space. Thus a Wentzell-Freidlin type large deviation principle is established utilizing certain results by Varadhan and Bryc.
