Estabilidade de equilíbrio e órbitas periódicas em um sistema Lotka-Volterra com duas presas e um predador
(2008)
Neste trabalho analisamos o sistema de equações differenciais com duas presas e um predador do tipo Lotka-Volterra, com e sem colheita. Inicialmente estudamos a estabilidade local e global dos pontos de equilíbrio no ...
Un método proximal continuo para minimizar funciones cuasi-convexas
(Universidad Nacional del CallaoPE, 2009)
Estudia la viabilidad de la trayectoria en el octante positivo y analiza su comportamiento asintótico donde obtenemos la convergencia global de la trayectoria para un punto óptimo cuando f es convexa. Además, extiende los ...
Periodic solutions of periodically harvested lotka-volterra systems
(Universidad Nacuional de Colombia; Sociedad Colombiana de matemáticas, 1987)
We study a Lotka-Volterra system with periodic harvesting, find sufficient conditions for the existence of periodic solutions with the same period, and, under certain conditions, count the number of such periodic solutions.
Mathematical modeling and control of population systems: Applications in biological pest control
(Elsevier B.V., 2008-07-01)
The aim of this paper is to apply methods from optimal control theory, and from the theory of dynamic systems to the mathematical modeling of biological pest control. The linear feedback control problem for nonlinear systems ...

Sobrevivencia en un sistema lotka- volterra bidimensional
(Universidad Nacuional de Colombia; Sociedad Colombiana de matemáticas, 2000)
A Lotka-Volterra system of integro-differential equations with constant coefficients and infinite delay is considered and asymptotic stability of the equilibrium point with both components are positive is investigated.
A NOTE ON SDRE CONTROL APPLIED IN PREDATOR-PREY MODEL: BIOLOGICAL CONTROL OF SPIDER MITE PANONYCHUS ULMI
(World Scientific Publ Co Pte Ltd, 2016-06-01)
The spider mite Panonychus ulmi (P. ulmi) is one of the most important pests of apple plantations. Studies suggested that spider mite Neoseiulus californicus (N. californicus) is able to control spider mite P. Ulmi, ...
