There is a phenomenon known as "eigenvalue avoidance" by which in many cases in these parametric plots the eigenvalues come very close to one another, but if one zooms in they don't actually meet. For instance, if you take two random symmetric matrices $A$, $B$ and plot the eigenvalues of $A+xB$ vs. $x$, you will see something similar. | |
