Asymptotical stability and asymptotic periodicity for the Lasota-Wazewska model of fractional order with infinite delays

open access: yes, 2020
In this paper, we study a class of nonlinear fractional-order LasotaWazewska model with infinite delays. Firstly, we introduce some definitions, lemmas of fraction-order differential equation and a number of properties of Mittag-Leffler function.

© Hindawi Publishing Corp. PERIODIC SOLUTIONS OF PERIODIC GENERALIZED FOOD LIMITED MODEL

open access: yes, 1999
. By using the continuation theorem of coincidence degree theory, the existence of positive periodic solutions for a periodic generalized food limited model with state dependent delays and distributed delays is studied, respectively.

© Hindawi Publishing Corp. PERIODIC SOLUTION FOR A DELAYED THREE-SPECIES FOOD-CHAIN SYSTEM WITH HOLLING TYPE-II FUNCTIONAL RESPONSE

open access: yes, 2002
A delayed three-species periodic food-chain system with Holling type-II functional response is investigated. By using Gaines and Mawhin’s continuation theorem of coincidence degree theory, a set of easily verifiable sufficient conditions is derived for ...

Periodicity , positivity and stability of solutions for some delay dynamic equations using the fixed point technique

open access: yes
This thesis focuses on examining the periodicity, positivity, and stability of solutions for specific delay dynamic equations on time scales. To achieve this, we initially introduce fundamental concepts pertaining to functional analysis, fixed point ...
