摘 要：對於一個給定的實數$x\in (0,1)$, 我們考慮一類單參數的康托集合族$C_\lambda $, 變動該參數$\lambda $使得$x\in C_\lambda $. 我們討論這樣的參數$\lambda $的性質.
Bifurcations in Recurrent Neural Network Involving Transcendental Functions
Weinian Zhang (張偉年)
Sichuan University (四川大學)
Abstract: In this talk we investigate bifurcations of a three-node recurrent neural network, in which the transcendental function tanh(x) and its iterates are involved. Those functions make computation so complicated that one hardly determine the number and distribution of all equilibria. We give a method to ignore the classic routine of discussion but display their saddle-node, pitchfork, and Hopf bifurcations.
異質性傳染病動力學模型與應用
Jing’an Cui (崔景安)
Beijing University of Civil Engineering and Architecture(北京建築大學)
摘 要：傳染病爆發的基本再生數與最終規模問題的研究對於傳染病的傳播與控製非常重要。針對異質的多種群傳染病模型探討基本再生數與最終規模的關系，應用於一些傳染病案例與免疫策略的研究。
Dynamic Modeling of COVID-19
Zhen Jin (靳 禎)
Shanxi University (山西大學)
Abstract: The outbreak of the Corona Virus Disease 2019 (COVID-19) epidemic began since last December that has spread the fastest, caused the most extensive infections and has a huge impact on the safety of human life. Dynamical modelling is one of the useful methods to reveal the transmission rule of COVID-19 spread which is based on the internal transmission mechanism and can dynamically predict the future trend according to the current information. In the talk, we will introduce some of the transmission dynamics models of COVID-19 under intervention: homogeneous mixed dynamics model, network dynamics model, and household dynamics model；We also evaluated isolation and other interventions measures.
