OLM. 4.3. Two age classes and a non-generic exception


As explained in TBox 4.3, the leading eigenvalue of the transition matrix provides the long-term growth rate of a structured population; the corresponding eigenvector determines the equilibrated population structure. This simple picture is not without exceptions. Here we consider a simple situation, where the two eigenvalues are of equal absolute value and the resulting behaviour is a population structure, which oscillates forever.
