Observability from measurable sets for strongly coupled parabolic systems via single-component observation
Xiaoyu Fu, Gengsheng Wang, Huaiqiang Yu +1
We establish an observability inequality from space-time measurable sets for a class of strongly coupled parabolic systems consisting of two equations, where the observation acts o…
Frequency-domain criterion on the stabilizability for infinite-dimensional linear control systems
Karl Kunisch, Gengsheng Wang, Huaiqiang Yu
A quantitative frequency-domain condition related to the exponential stabilizability for infinite-dimensional linear control systems is presented. It is proven that this condition…
Stabilizability of linear systems with discrete observation mode
Hanbing Liu, Gengsheng Wang, Huaiqiang Yu
For linear control systems, the usual state feedback stabilizability has two components: one is a continuous observation mode (i.e., to observe solutions continuously in time), and…
Feedback law to stabilize linear infinite-dimensional systems
Yaxing Ma, Gengsheng Wang, Huaiqiang Yu
We design a new feedback law to stabilize a linear infinite-dimensional control system, where the state operator generates a C0-group and the control operator is unbounded. Our fee…
Unique continuation inequalities for the parabolic-elliptic chemotaxis system
Gengsheng Wang, Guojie Zheng
This paper studies the quantitative unique continuation for a semi-linear parabolic-elliptic coupled system on a bounded domain. This system is a simplified version of the chemotax…
Observability for heat equations with time-dependent analytic memory
Gengsheng Wang, Yubiao Zhang, Enrique Zuazua
This paper presents a complete analysis of the observability property of heat equations with time-dependent real analytic memory kernels. More precisely, we characterize the geomet…
