Question: A common model for fish population is given by the Ricker equation Nn 1 = alpha e^((-beta*Nn)*Nn), Assume Nn is rescaled so that beta =1.

A common model for fish population is given by the Ricker equation Nn 1 = alpha e^((-beta*Nn)*Nn), Assume Nn is rescaled so that beta =1. a) Calculate the fixed point(s) of this model for general alpha. When is ther a positive fixed point? b)Determine a condition for local stability of the positive fixed point N in terms of alpha. You do not need to solve for alpha, just simplify reasonably
