FIG. 1.

A generic picture for the function f(z) for positive and negative a, common b, c, d > 0 and λ = b 2 c/(1 + b 2 + b 2 c 2). The left curve represents f(z) for a > 0 and the right curve for a < 0. The two curves meet at three points with abscissae z = 0, c/(1 + c 2), (1 + d 2)/c. The three roots of f(z) are for a < 0, and for a > 0.
