Streszczenie
It is explained that the following two problems are equivalent:
(i) describing all affine rulings of any given weighted projective plane;
(ii) describing all weighted-homogeneous locally nilpotent derivations of ${\bf k}[X,Y,Z]$.
Then the solution of (i) is sketched. (Outline of our joint work with Peter Russell.)
