A partial differential equation model with age-structure and nonlinear recidivism: Conditions for a backward bifurcation and a general numerical implementation
(2019-12-15)
We formulate an age-structured three-staged nonlinear partial differential equation model that features nonlinear recidivism to the infected (infectious) class from the temporarily recovered class. Equilibria are computed, ...
Backward bifurcation in neutrophil-pathogen interaction

Assessing the effects of multiple infections and long latency in the dynamics of tuberculosis
(2010-05)
In order to achieve a better understanding of multiple infections and long latency in the dynamics of Mycobacterium tuberculosis infection, we analyze a simple model. Since backward bifurcation is well documented in the ...

Time-periodic perturbation of a Lienard equation with an unbounded homoclinic loop
(Elsevier B.V., 2011-08-15)
We consider a quadratic Lienard equation with an unbounded homoclinic loop, which is a solution tending in forward and backward time to a non-hyperbolic equilibrium point located at infinity. Under small time-periodic ...
