Existence of Positive Periodic Solutions for the SIV Epidemic Model with Impulsive Vaccination and Infection-Age

In this paper, we discuss the SIV epidemic model with impulsive vaccination and infection-age. Bifurcation theory and Lyapunov-Schmidt series expansion are used to show the existence of the positive periodic solutions under some conditions.

EXISTENCE AND NONEXISTENCE OF POSITIVE RADIAL SOLUTIONS FOR A CLASS OF SEMILINEAR ELLIPTIC SYSTEMS

In this paper an existence theorem of positive radial solutions to a class of semilinear elliptic systems is proved by the Leray-Schauder degree theorem. Also, a nonexistence theorem is obtained. As an application of the main theorem, an example is given.     

Existence of Positive Periodic Solutions of Competitor-Competitor-Mutualist Lotka-Volterra Systems with Infinite Delays

In this paper,the authors primarily explore a delayed competitor-competitor-mutualist Lotka-Volterra model,which is a system of differential equation with infinite integral.The authors first study the existence of positive periodic solutions of the model by using the Krasnoselskii’s fixed point theorem,and then present an example to illustrate the main results.     

PERIODIC SOLUTIONS AND GLOBAL ASYMPTOTIC STABILITY OF A DELAYED DISCRETE PREDATOR-PREY SYSTEM WITH HOLLING II TYPE FUNCTIONAL RESPONSE

In this paper, we study the existence and global asymptotic stability of positive periodic solutions of a delayed periodic predator-prey system with Hoffing Ⅱ type functional response. By use of the continuation theorem of coincidence degree theory and the method of Lyapunov function, some sufficient conditions are obtained.     

马氏转移高敏感跳扩散CKLS模型的解及金融应用

将马氏转移切换机制和泊松过程引入到CKLS短期利率模型中,构建马氏转移跳扩散CKLS模型.理论方面,利用Lyapunov函数方法证明了马氏转移跳扩散CKLS模型存在唯一的全局正解并给出了该解的分析性质(包括一阶矩二阶矩的有界性,随机有界性和路径估计);用欧拉离散化方法得到马氏转移跳扩散CKLS模型的欧拉数值解,证明了其依概率收敛于解析解.应用方面,以债券定价和障碍期权的期望收益为例给出了马氏转移跳扩散CKLS模型数值解的收敛性在金融领域中的应用.基于7天Shibor利率的实证分析,说明了马氏转移跳扩散CKLS模型对我国金融市场中动态利率建模更加合理和有效.

Existence of solutions of generalized quasi-variational relation problems by the inductive relations and some applications

By the inductive relations, this paper first obtains some existence theorems of solutions for generalized quasi-variational relation problems, which are different from other papers. As applications, some existence theorems of solutions for generalized quasi-equilibrium problems and NS-equilibria for noncooperative games under uncertainty are obtained.
