An Extensive Study of Approximating the Periodic Solutions of the Prey -Predator System

, 2010
In this paper, an approximation to the periodic solutions of the general LotkaVolterra prey -predator system is obtained using the Poincare -Lindstedt method.

Coupled reaction-diffusion waves in a chemical system via fractional derivatives in Liouville-Caputo sense

, 2018
In this paper, we have generalized the fractional cubic isothermal auto-catalytic chemical system (FCIACS) with Liouville-Caputo, CaputoFabrizio-Caputo, and Atangana-Baleanu-Caputo fractional time derivatives, respectively. We apply the Homotopy Analysis

Planar Analytic Nilpotent Germs Via Analytic First Integrals

, 2004
1991 Mathematics Subject Classification. Primary: 34A25, 34A34, 37C10.We generalize the results of [6] by giving necessary and sufficient conditions for the planar analytic nilpotent germs to have an analytic first integral in (R[2], 0).

The Conley Index Over A Base

, 1996
We construct a generalization of the Conley index for flows. The new index preserves information which in the classical case is lost in the process of collapsing the exit set to a point. The new index has most of the properties of the classical index. As

Absolute concentration robustness and multistationarity in reaction networks: Conditions for coexistence

European Journal of Applied Mathematics
Many reaction networks arising in applications are multistationary, that is, they have the capacity for more than one steady state, while some networks exhibit absolute concentration robustness (ACR), which means that some species concentration is the ...

The Conley Index Over The Circle

, 1997
We study the Conley index over a base in the case when the base is the circle. Such an index arises in a natural way when the considered flow admits a Poincar'e section.

Integrated intelligent neuro-evolutionary computing approach to study SEIRC model representing campylobacteriosis transmission dynamics

Applied Mathematics in Science and Engineering
The objective of the presented study is to develop a neuro-evaluation-based algorithm for the mathematical solution of the SEIRC model that describes the dynamics of campylobacteriosis transmission (CBT) using the artificial neural network along with log-

A Becker–Döring model with injection and irreversible fragmentation

European Journal of Applied Mathematics
We introduce and analyse a variant of the Becker–Döring equations that models the growth of clusters through the gain or loss of monomers. Motivated by enzymatic reactions in biology, this model incorporates irreversible fragmentation and monomers ...
