Eigenvalue Analysis
The eigenvalues of the transition matrix provide a more precise means of analyzing the problem. Let's be sure we have the original transition matrix:
> owldat();
The eigenvalues of this matrix are found to be:
> eigenvalues( A );
To determine the long time behavior of this population it suffices to look at the magnitude of each of the eigenvalues:
> map( abs, [eigenvalues(A)] );
Since all three eigenvalues are less than 1 in absolute value, all populations will eventually decay to zero.
