Consider a nonlinear system for two populations with equilibrium points (0, 0), (0, N), (,), and Jacobian
x
J(x, y) = [
-2x+y
-y
-x+N-2y]
a) What is the critical bifurcation value, No, which changes the number of eq. pts.?
b) Evaluate the Jacobian at each equilibrium point and determine eq, pt. type for N>N₂:
(0,0) is a
(O.N) is a
() is a.
c) Sketch the geometric behavior of these solutions in the first quadrant of the phase plane (y vs x) for N-2.
