Question

Disease Spread With Recovery Consider the far more likely scenario in which a disease is circulating in a population, in such a way that individuals recover from the disease unharmed but are susceptible to reinfection. Again, let It denote the fraction of infected individuals in the population at time t. A discrete-time dynamical system which models this scenario is given by It+1 = It + bIt(1 - It) - kIt where the positive parameter b represents the per capita rate at which susceptible member of the population is infected, and the positive parameter k represents the rate at which infected individuals recover. Note that both b > 0 and k > 0. 4. Again let b = 0.5, and find the equilibrium points for this new system algebraically (your answers will depend on the parameter k).

Consider the far more likely scenario in which a disease is circulating in a population, in such a way that individuals recover from the disease unharmed but are susceptible to reinfection.
Again, let It denote the fraction of infected individuals in the population at time t. A discrete-time dynamical system which models this scenario is given by
It+1 = It + bIt(1 - It) - kIt
where the positive parameter b represents the per capita rate at which susceptible member of the population is infected, and the positive parameter k represents the rate at which infected individuals recover. Note that both b > 0 and k > 0.
4. Again let b = 0.5, and find the equilibrium points for this new system algebraically (your answers will depend on the parameter k).
