| Abstract: | LetX⊃P r be a non-degenerate variety and Γ(X) the closure inX of the set of all pointsP∈X such that the projection ofX fromP is not birational. Here we study the irreducible components of Γ(X), using proofs and ideas contained in a paper by Calabri and Ciliberto concerning the outer non birational projections. The author was partially supported by MIUR and GNSAGA of INdAM (Italy). |
