STABILITY ANALYSIS AND FLIP BIFURCATION OF A DISCRETE-TIME PREY-PREDATOR MODEL WITH PREDATOR IMMIGRATION | Asian Journal of Mathematics and Computer Research

 Aims: In this paper, a discrete-time prey-predator model with predator immigration has been considered.

Methodology: The model was mathemati-cally analysed and simulated in Mapple.

Results: The complex dynamical behavior of the presented model has been analyzed. Stability and existence of coexistence positive fixed point have been investigated. Moreover, using bifurcation theory, it has been shown that the model undergoes Flip bifurcation. Also, direction of Flip bifurcation has been given. Some numerical simulations including bifurcation diagrams, phase portraits and maximum Lyapunov exponents of the model have been given to support of the

analytical finding. The computation of the maximum Lyapunov exponents has confirmed the presence of chaotic behavior in the system.

Conclusion: The model was successfully built, analysed and simulated showing results that matched the theory.

FIXED POINT RESULTS ON A CLOSED BALL IN K-SEQUENTIALLY-COMPLETE PREORDERED QUASI-PARTIAL METRIC SPACES

Fixed point results for the self dominated mappings satisfying locally Hardy Roger type contractive conditions on a closed ball in K-sequentially 0-complete preordered quasi-partial metric space have been established. An example has been given. Many well-known recent results have been generalized.
