6.M. Bifurcation Diagram of a Discontinuous Function

If we break the tent map, making it discontinuous, and replacing the left side with a section of the logistic map

we obtain a much more interesting bifurcation diagram. The right side looks very similar to that of the tent map, but what about the left side? Here is the bifurcation diagram, and two successive magnifications.

The position of the jump from logistic map to tent map certainly has an influence on the bifurcation diagram. Here we move the jump from x = 0 to x = 1 in steps of 0.02.

We introduce this example to show giving up continuity, a questionable assumption in many real applications, can introduce entirely new behaviors.
