非一致扩张映射不变密度的严格逐点逼近

Rigorous pointwise approximations for invariant densities of nonuniformly expanding maps

Wael Bahsoun, Christopher Bose, Yuejiao Duan

摘要:

我们使用一个Ulam型离散化方案,提供逐点逼近的不变密度的区间映射的中性不动点。我们证明了近似不变密度以$C^*\cdot\frac{\ln m}{m}$的速率逐点收敛到真密度,其中$C^*$是可计算的固定常数,$m^{-1}$是离散化的网格步长。

英文摘要:

We use an Ulam-type discretization scheme to provide pointwise approximations for invariant densities of interval maps with a neutral fixed point. We prove that the approximate invariant density converges pointwise to the true density at a rate $C^*\cdot\frac{\ln m}{m}$, where $C^*$ is a computable fixed constant and $m^{-1}$ is the mesh size of the discretization.
