Phase Plane Analysis on Time Scales for a Lotka-Volterra Competition Model
Sabrina Streipert, Gail S. K. Wolkowicz
In this work, we formulate a two-species Lotka--Volterra competition model on time scales. To derive the global dynamics of solutions of this planar model, we introduce a dynamic a…
Adding a fecundity-survival trade-off to a discrete population model with maturation delay
Christopher J. Greyson-Gaito, Sabrina H. Streipert, Gail S. K. Wolkowicz
Although maturation delays are frequently included in population models, researchers rarely account for mortality between birth and maturity. Previous discrete population models ha…
An augmented phase plane approach for discrete planar maps: Introducing next-iterate operators
Sabrina H. Streipert, Gail S. K. Wolkowicz
The next-iterate operators and corresponding next-iterate root-sets and root-curves associated with the nullclines of a planar discrete map are introduced. How to augment standard…
An alternative delayed population growth difference equation model
Sabrina H. Streipert, Gail S. K. Wolkowicz
We propose an alternative delayed population growth difference equation model based on a modification of the Beverton-Holt recurrence, assuming a delay only in the growth contribut…
Exact Solution to a Dynamic SIR Model
Martin Bohner, Sabrina Streipert, Delfim F. M. Torres
We investigate an epidemic model based on Bailey's continuous differential system. In the continuous time domain, we extend the classical model to time-dependent coefficients and p…
