Quantitative unique continuation property for fourth-order Baouendi-Grushin type subelliptic operators with a potential

Yusheng Qiu, Jinggang Tan, Aliang Xia

We investigate the quantitative unique continuation property for solutions to $Δ_{X}^{2} u = V u,$ where $Δ_{X} = Δ_{x} + ∣ x ∣^{2 β} Δ_{y}$ ( $0 < β \leq 1$ ), with $x \in \mathbb{R}^{m…

Decorated Marked Surfaces with vortices: Cluster braid group vs. braid twist group

Yu Qiu, Yu Zhou

Let $S$ be a marked surface with vortices (=punctures with extra $Z_{2}$ symmetry). We study the decorated version $S_{△}$ , where the $\mathbb{Z…

From green mutation to $X$ -evolution: flows and foliations on cluster complexes

Yu Qiu, Liheng Tang

For any point $X$ in the cluster complex $Cpx (C)$ of a 2-Calabi-Yau category $C$ , we introduce $X$ -evolution flow on $\mathrm{Cpx}(\m…
