Huang's conjecture. The matrix differential Harnack estimate should hold for this hypoelliptic operator.

A UFG process is a diffusion process satisfying the UFG condition, and its lack of smoothness refers to the failure of its law to have a smooth density in the absence of the Hörman…

Let $S=\mathbb{R}^2\times\mathbb{S}_1$, let $(X_t)_{t\geq 0}$ be the diffusion on $S$ associated with the melt-spinning SDE, and let $\mu$ be the invariant distribution given by ……
