%0 Journal Article %T Bifurcation analysis in a discrete SIR epidemic model with the saturated contact rate and vertical transmission %A Du, Wenju %A Zhang, Jiangang %A Qin, Shuang %A Yu, Jianning %J Journal of Nonlinear Sciences and Applications %D 2016 %V 9 %N 7 %@ ISSN 2008-1901 %F Du2016 %X The aim of paper is dealing with the dynamical behaviors of a discrete SIR epidemic model with the saturated contact rate and vertical transmission. More precisely, we investigate the local stability of equilibriums, the existence, stability and direction of flip bifurcation and Neimark-Sacker bifurcation of the model by using the center manifold theory and normal form method. Finally, the numerical simulations are provided for justifying the validity of the theoretical analysis. %9 journal article %R 10.22436/jnsa.009.07.02 %U http://dx.doi.org/10.22436/jnsa.009.07.02 %P 4976--4989
