Mean-field control with common noise and filtering problems naturally lead to second-order PDEs on Wasserstein space. In this talk, we analyze a class of such equations in which the second-order operator is finite-dimensional in nature. We establish comparison principles and apply them to obtain particle convergence rates in mean-field control. The talk is based on joint work with Erhan Bayraktar, Ibrahim Ekren, and Xihao He.
