| contents | In the literature there are two definitions of well formed varieties in weighted projective spaces. According to the first one, well formed variety is the one whose intersection with the singular locus of the ambient weighted projective space has codimension at least two, while, according to the second one, well formed variety is the one who does not contain in codimension one a singular stratum of the ambient weighted projective space. We show that these two definitions indeed differ, and show that they coincide for quasi-smooth weighted complete intersections of dimension at least 3. |
