对于真实的解析扩展区间映射,给出了一种新的严格逼近真实的解析观测量扩散系数的方法。作为一个理论算法,我们的近似计划是给二次指数收敛的扩散系数。转换为明确的高精度严格的界限,这种快速收敛的方法示出在设置兰福德的地图(模1)。
For real analytic expanding interval maps, a novel method is given for rigorously approximating the diffusion coefficient of real analytic observables. As a theoretical algorithm, our approximation scheme is shown to give quadratic exponential convergence to the diffusion coefficient. The method for converting this rapid convergence into explicit high precision rigorous bounds is illustrated in the setting of Lanford's map (mod 1).
