It occurs that these curves are projectively rigid. We also discuss the general problem of projective rigidity of rational cuspidal plane curves.LaTeX 30 pages, author-supplied DVI file available at http://www.math.duke.edu/preprints/95-00.dviAlgebraic Geometry14H45 (Primary) 14H10, 14H20, 14J25, 14N05 (Secondary)text
