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 $${\Delta }_X^{2}u=Vu,$$ where ${\Delta }_X={\Delta }_x+|x{|}^{2\beta }{\Delta }_y$ ($0<\beta \le 1$), with $x \in \mathbb{R}^{m…
