Research on the Dynamical Behavior of Discrete SEI TB Model Based
on the Difference Equation Theory
Abstract: This paper mainly uses the difference equation stability theory to analyze the dynamical behavior of discrete SEI model of tuberculosis, Firstly, the basic reproduction number is defined. Then using the Jury Criterion, the free disease free equilibrium is locally stable when .Finally the global stability of the endemic equilibrium is judged using the numerical simulation by MATLAB.
Key words: Discrete epidemic model; Basic reproductive number; Stability
