On the mean field limit of the Random Batch Method for interacting particle systems
نویسندگان
چکیده
The Random Batch Method proposed in our previous work (Jin et al. J Comput Phys, 2020) is not only a numerical method for interacting particle systems and its mean-field limit, but also can be viewed as model of the system which particles interact, at discrete time, with randomly selected mini-batch particles. In this paper, we investigate limit number N→∞. Unlike classical mean field where law large numbers plays role chaos propagated to later times, now does rely on imposed every time. Despite this, will justify (discrete time) show that time interval τ → 0, approaches solution nonlinear Fokker-Planck equation arising original Wasserstein distance.

Mean Field Limit for Stochastic Particle Systems
We review some classical and more recent results for the derivation of mean field equations from systems of many particles, focusing on the stochastic case where a large system of SDE’s leads to a McKean-Vlasov PDE as the number N of particles goes to infinity. Classical mean field limit results require that the interaction kernel be essentially Lipschitz. To handle more singular interaction ke...
متن کاملMean-field Limit versus Small-noise Limit for Some Interacting Particle Systems
In the nonlinear diffusion framework, stochastic processes of McKean-Vlasov type play an important role. Such diffusions can be obtained by taking the hydrodymamic limit in a huge system of linear diffusions in interaction. In both cases, for the linear and the nonlinear processes, small-noise asymptotics have been emphasized by specific large deviation phenomenons. The natural question, theref...

قاعده مقتضی و مانع در متون فقهی کم و بیش مستند احکام قرار گرفته و مورد مناقشه فقهاء و اصولیین می باشد و مشهور معتقند مقتضی و مانع، قاعده نیست بلکه یکی از مسائل ذیل استصحاب است لذا نگارنده بر آن شد تا پیرامون این قاعده پژوهش جامعی انجام دهد. به عقیده ما مقتضی دارای حیثیت مستقلی است و هر گاه می گوییم مقتضی احراز شد یعنی با ماهیت مستقل خودش محرز گشته و قطعا اقتضاء خود را خواهد داشت مانند نکاح که ...
