Bilinear control of age--space structured populations
Jiguang Yu, Louis Shuo Wang, Ye Liang
We study constrained bilinear optimal control for nonlocal age--space structured population equations with renewal boundary conditions and endogenous surveillance feedback. The con…

Size-Selective Threshold Harvesting under Nonlocal Crowding and Exogenous Recruitment
Jiguang Yu, Louis Shuo Wang, Ye Liang
We propose a nonlinear size-structured fishery model for externally recruited stocks under size-selective harvesting. The population density satisfies a McKendrick--von Foerster tr…

Age-Structured Harvesting Models: A Structural Comparison of Rate-Control and Effort-Control Optimality Systems
Jiguang Yu, Louis Shuo Wang, Ye Liang
We study optimal harvesting in continuous-time, age-structured population models of McKendrick--von Foerster type, and we compare two harvesting mechanisms. In the \emph{rate-contr…
