Stability of Fourier Restriction for a Class of Finite Type Surfaces in
Wenjuan Li, Hongqiang Wang, Huiju Wang
We establish the stability of the optimal non-endpoint Fourier restriction range under smooth flat perturbations of curved-root surfaces in . Specifically, we consider…
Endpoint weighted Fourier estimate with vanishing spherical trace
Wenjuan Li, Manli Song, Hongqiang Wang +1
We establish an endpoint weighted Fourier estimate under a vanishing restriction condition on the unit sphere. Let and . We prove that every $f \in L…
A Study on Kakeya Needle Problem for -Rectifiable Sets
Wenjuan Li, Hongqiang Wang, Huiju Wang
In this article we study the analog of Kakeya needle problem for -rectifiable sets in and construct the related Nikodym type sets. The novelty of our approach…
A Two-Layer Electrostatic Film Actuator with High Actuation Stress and Integrated Brake
Huacen Wang, Hongqiang Wang
Robotic systems driven by conventional motors often suffer from challenges such as large mass, complex control algorithms, and the need for additional braking mechanisms, which lim…
