我们收集了一些关于二次费用的最优运输的例子,以探讨单位映射作为最优运输的稳定性。首先,我们考虑在区域的正则部分附近的密度和区域扰动。其次,我们研究了非正则区域的密度和区域变形。在这里,我们将注意力限制在两个维度上,并将注意力集中在90个$$∘角附近。
We collect some examples of optimal transports for quadratic cost in order to explore the stability of the identity map as an optimal transport. First, we consider density and domain perturbations near regular portions of domains. Second, we investigate density and domains deformations to non-regular parts of domains. Here, we restrict our attention to two dimensions and focus near 90$$^{\circ }$$∘ corners.
