The renormalization group is a set of tools that can be used to incorporate the effect of fluctuations in a dynamical system as a rescaling of the system's parameters. Here, we apply the renormalization group to a pattern-forming stochastic cubic autocatalytic reaction-diffusion model and compare its predictions with numerical simulations. Our results demonstrate a good agreement within the range of validity of the theory and show that external noise can be used as a control parameter in such systems.
重整化群是一组工具，可用于将动力学系统中波动的影响纳入系统参数的重新缩放中。在这里，我们将重整化群应用于形成图案的随机立方自催化反应-扩散模型，并将其预测与数值模拟进行比较。我们的结果表明，在理论的有效范围内具有良好的一致性，并表明外部噪声可作为此类系统中的控制参数。
