Plane curves whose singular points are cusps and triple coverings of ℙ2

  • Hisao Yoshihara


We study a plane curve C whose singular points are cusps and the surface which is a triple covering of ℙ2 branched along C. As a result, especially we obtain an inequality for the sum of the Milnor numbers at the singularities of C and new surfaces of general type.
