Title: Properties of non-Schwarzschild gravitational lenses
Abstract: The focusing properties of very simple non-Schwarzschild gravitational fields are considered. Such gravitational lenses would have some interesting features. In particular, it is shown for the first time that two-dimensional caustics would exist; they should be taken into account when assessing the probability that the gravitational-lens effect might be observable. Certain errors and inaccurate statements by previous authors are pointed out. (AIP)
