EXISTENCE OF PERIODIC SOLUTION OF SOME ECO-EPIDEMIOLOGICAL SYSTEMS
Zhijun Liu,Sahabuddin Sarwardi 한국전산응용수학회 2010 Journal of applied mathematics & informatics Vol.28 No.5
The effect of impulse in the ecological models makes them more realistic. Recently, the eco-epidemiological models have become an important field of study from the both mathematical and ecological view points. In this article, we consider some eco-epidemiological systems under the influence of impulsive force. A set of sufficient conditions for the permanence of the system are derived. Stability of the trivial solution and at least one strictly positive periodic solution are obtained. Numerical examples are given in support to our analytical findings. Finally, a short discussion concludes the paper.

MEAN SQUARE STABILITY IN A MODIFIED LESLIE-GOWER AND HOLLING-TYPE II PREDATOR-PREY MODEL
Pallav Jyoti Pal,Sahabuddin Sarwardi,Tapan Saha,Prashanta Kumar Mandal 한국전산응용수학회 2011 Journal of applied mathematics & informatics Vol.29 No.3
Of concern in the paper is a Holling-Tanner predator-prey model with modified version of the Leslie-Gower functional response. Dynamical behaviours such as stability, permanence and Hopf bifurcation have been carried out deterministically. Using the normal form theory and center manifold theorem, the explicit formulae determining the stability and direction of Hopf bifurcation have been derived. The deterministic model is extended to a stochastic one by perturbing the growth equation of prey and predator by white and colored noises and finally the mean square stability of the stochastic model systems is investigated analytically. An extensive quantitative analysis has been performed based on numerical computation so as to validate the applicability of the proposed mathematical model.
