Global analysis of a discrete sirs epidemic model with nonlinear incidence rate

Butsayapat Chaihao (Chulalongkorn University, 2021)

In this thesis, we prove some behaviors of a discrete SIRS epidemic model with a nonlinear incidence rate and a distributed time-delay. This model is constructed from the discretization of the corresponding continuous model ...
Local attractivity and periodic character of rational Difference equation

Butsayapat Chaihao (Chulalongkorn University, 2016)

In this thesis, we investigate some behaviors of the rational difference equations [symbol] where k ∈ℕ, the parameters A,B0,B1,B2, . . . ,Bk, and the initial conditions x−k, x−k+1, x−k+2, . . . ,x0 are nonnegative real ...
