Stability Analysis of Abstract Systems with Local Damping题目:Stability Analysis of Abstract Systems with Local Damping报告人:张琼 教授(北京理工大学)地点:致远楼103室时间:2026年5月20日 星期三 10:45Abstract:We study the stability properties of general systems with local damping. For a single abstract system subject to local damping, we establish polynomial decay rates for the associated semigroup via precise resolvent estimates. We further cons...张琼 教授(北京理工大学)致远楼103室2026年5月20日 星期三 10:45

Dynamic Sharpe Ratio Optimization题目:Dynamic Sharpe Ratio Optimization报告人:Prof. Harry Zheng(Imperial College London)地点:致远楼103室时间:2026年4月22日 星期三 15:00-16:00Abstract:We study a dynamic Sharpe ratio optimization problem in the presence of unhedgeable background risk. We derive the time-consistent HJB equation and characterize the corresponding equilibrium strategy. For two economically relevant special ...Prof. Harry Zheng(Imperial College London)致远楼103室2026年4月22日 星期三 15:00-16:00
