Daily quote by Solomon Lefschetz

• The numerical relations existing between ordinary or so-called Plückerian singularities of a plane curve were determined as early as 1834 by PLÜCKER, but the inverse question has been left almost untouched. It may be stated thus: To show the existence of a curve having assigned Plückerian characters; and is equivalent to the determination of the maximum of cusps κ_M that a curve of order m and genus p may have. VERONESE ... has solved the question for rational curves.
