About the Cover

It is possible to deform a plane in three-space into a ruled surface containing one triple point and two pinch points using the equations (x, y³ - cy, xy + y⁵ - cy³), as described in the work of David Mond and Washington Marar. This rendering was produced at the Geometry Center by Thomas Banchoff of Brown University and Davide Cervone of Union College. It was included in the show "Surfaces Beyond the Third Dimension" at the Providence Art Club in March 1996.
