H. Mete Soner, Qinxin Yan

AI总结:

摘要:

具有可分离结构的平均场控制问题的动态规划方程是Wasserstein空间上的Eikonal方程。使用线性导数的标准微分法产生了经典粘性理论的直接扩展。我们利用测度空间上Sobolev范数的Fourier表示,以及有限维理论的标准技术,获得了在Wasserstein-1范数中Lipschitz连续的下解和上解之间的比较结果,该连续性已直接对值函数进行了验证。一个关键技术结果给出了一个函数的线性导数的导数的逐点上界,该上界以其Lipschitz范数表示。

英文摘要:

Dynamic programming equations for mean field control problems with a separable structure are Eikonal equations on the Wasserstein space. Standard differentiation using linear derivatives yield a direct extension of the classical viscosity theory. We use Fourier representation of the Sobolev norms on the space of measures, together with the standard techniques from the finite dimensional theory to obtain a comparison result among sub and super solutions that are Lipschitz continuous in the Wasserstein-one norm which is directly verified for the value function. A key technical result provides a point-wise upper bound for the derivative of the linear derivative of a function in terms of its Lipschitz norm.
