Centre Symmetry Sets of Families of Plane Curves
... The situation at a special point on the y-axis must be different, since there, the local picture of the CSS for ε “ 0 is a line (the y-axis) and a parabolic curve by Proposition 3.4, and in fact, the big CSS is singular. ...

The determination of the intersection of projective plane P2 (K) curves based on the bezout's theorem
... The question on the number of points of intersection had been the subject of conjecture for some time earlier, and it was expected that two plane curves of respective total degrees m and n in some sense had ...
