Dynamical analysis of a fractional-order eco-epidemiological model with disease in prey population
A fractional-order eco-epidemiological model with disease in the prey population is formulated and analyzed. Mathematical analysis and numerical simulations are performed to clarify the characteristics of the proposed fractional-order model.

Global Dynamics and Bifurcations of an Oscillator with Symmetric Irrational Nonlinearities
This study’s objective is an irrationally nonlinear oscillating system, whose bifurcations and consequent multi-stability under the circumstances of single potential well and double potential wells are investigated in detail to further reveal the ...

Hopf bifurcation analysis in a predator–prey model with time delay and food subsidies
We analyze the stability of positive equilibrium in a predator-prey model with time delay τ and subsidies. The sufficient conditions of the local Hopf bifurcations at the positive equilibrium are obtained.

Analysis of a Heterogeneous Trader Model for Asset Price Dynamics
We examine an asset pricing model of Westerhoff (2005). The model incorporates heterogeneous beliefs among traders, specifically fundamentalists and trend-chasing chartists. The form of the model is shown here to be a nonlinear planar map.

Bifurcations and Invariant Sets in a Class of Two-Dimensional Endomorphisms
Several endomorphisms of the plane have been constructed by simple maps. We study the dynamics occuring in one of them, which is rich in global bifurcations.

Asset price dynamics in a financial market with fundamentalists and chartists
In this paper we consider a model of the dynamics of speculative markets involving the interaction of fundamentalists and chartists. The dynamics of the model are driven by a two-dimensional map that in the space of the parameters displays regions of ...

Scientific legacy of L. P. Shilnikov: to the 90th anniversary [PDF]
This year we celebrate the 90th anniversary of Leonid Pavlovich Shilnikov (1934-2011), an outstanding Russian mathematician and one of the founders of the mathematical theory of dynamic chaos and the theory of global bifurcations of multidimensional ...

Stability and Hopf bifurcation of a two species malaria model with time delays
We present a mathematical model of the transmission dynamics of two species of malaria with time lags. The model is equally applicable to two strains of a malaria species.

Bifurcations of Nonconstant Solutions of the Ginzburg-Landau Equation
We study local and global bifurcations of nonconstant solutions of the Ginzburg-Landau equation from the families of constant ones. As the topological tools we use the equivariant Conley index and the degree for equivariant gradient maps.
