Effect Of Random Factors On The Transmission Of Feline Immunodeficiency Virus

In this thesis, we mainly studies the effect of random factors on feline immunodeficiency virus, the existence of the unique positive so-lution of the stochastic model is proved, and the asymptotic behavior of positive solutions and existence of periodic solution. There are five chapters:In Chapter 1, simply introduce the background and significance of stochastic FIV models. The main problems involved in this paper are also described briefly.In Chapter 2, mainly gives some pre-knowledge needed in this paper.In Chapter 3, study the dynamics behavior of fiv affected by random factors, the existence of the unique positive solution of the stochastic model is proved, and the asymptotic behavior of positive solutions .In Chapter 4, the existence of periodic solution for seasonal vari-ation is studied..In chapter 5, we summarize the paper.
