Homework assignment 3 * Due date: Monday April 13, 2009. 1. In class we solved McKendrick’s problem: u a ( a,t ) + u t ( a,t ) = - d ( a ) u ( a,t ) , with BC : u (0 ,t ) = B ( t ) , and IC : u ( a, 0) = u 0 ( a ) . Here we consider the special case where the survival function is exponential: l ( a ) = e - μa , for some μ > 0 . Find the instantaneous death rate d ( a ). Find the basic reproduction number R 0 (i.e. the expected number of offspring per female over her lifetime) if the maternity function is given by:
