tailieunhanh - Kahler differential modules and configurations of points in P2

Given a finite set of points in the projective plane, we use the module of Kahler differentials to investigate the configurations of these points. More precisely, depending on the values of the Hilbert function of the module of Kahler differential 3-forms, we determine whether the set of points lies on a non-singular conic, or on two different lines, or on single line. |
