Investment Portfolio Management: Brief Introduction and New ResultsPart I will give the brief introduction to portfolio management problem, including importance of finance, financial bubbles, key factors of investment, theory and problems. Part II will deal with a multi-period portfolio management problem over a finite horizon. The objective is to seek the optimal investment policy series which maximizes the weighted sum of a linear combination of the expected return and the variance of portfolio over all the investment periods.王庆国博士致远楼102室6月12日(周日)上午9:40

Analysis of Coupled Degenerate Reaction-diffudion SIR Model Describing Popula...A coupled degenerate reaction-diffudion SIR model for the overall dynamics of the interaction between fox rabies is considered. The model helps to explain the epidemiological patterns observed in Europe, including 3 to 5 year cycle in fox populations infected with rabies. We provided some global analysis of the model, including the asymptotical behaviors due to Hopf bifurcation in the homogeneous model bescribed by a set of ordinary differential equations.衣凤岐教授致远楼102室6月8日(星期三),上午9:00-10:00

Minimal Surfaces in the Three-dimensional Heisenberg Group and the Bernstein ...We will characterize minimal surfaces in the Heisenberg group by the harmonicity of the normal Gauss map, considered as a map from the surface to the hyperbolic spaceH2. This comes with a close relationship with constant mean curvature surfaces in Minkowski space R13. Using this relationship one can translate very directly the Bernstein solution of Tom Wan to the Heisenberg group.Josef Dorfmeister教授致远楼107室2016年6月2日(周四)下午15:30-16:30

High Dimensional Empirical LikelihoodIn this talk, by adding two pseudo-observations to the original data set, I will talk about the asymptotic normality of the log empirical likelihood ratio statistic. In practise, I suggest to use the normalized F distribution to approximate the distribution of the log empirical likelihood ratio statistic. Simulation results show the excellent performance of this approximation.Professor Zhou Wang致远楼102室2016年5月31日(周二)下午16:00
