Questions and Assignments to Lecture 9

9.1. Population dynamics is simulated by the differential equation:

Draw schematically the phase portrait (rate of population growth vs. population density). Find all equilibrium points and characterize their stability.

9.2. Characterize the type of attractor in population dynamics: (a) stable equilibrium; (b) limit cycle, (c) chaos.
