We develop a Mathematical model showing the main dynamical regimes of the weed Opuntia stricta and the insect, Dactylopius opuntiae interaction. We prove that under appropriate conditions a positive solution of the system ...

We develop a fishery model with price dependent harvesting by formulating a system of three differential equations describing its dynamics. Assuming that the price of the harvested fish on the market evolves relatively ...

ABSTRACT: We consider the synchronization and cessation of oscillation of a positive even number of planar oscillators that are coupled to their nearest neighbours on one, two, and three dimensional integer lattices via ...
