Equilibrium Values in Systems of Difference Equations
Not what you're looking for?
Consider the interaction of two species whose populations after n years are represented by the numbers xn and yn. Consider the following model:
xn+1 = 0.8xn + 0.002xnyn
yn+1 = 0.9yn + 0.001xnyn
x0 = 50
y0 = 100
Iterate the system. Can the two species coexist? Is there an equilibrium value?
