Degenerate Varieties

In this chapter we investigate the Hadamard products of degenerate subvarieties \(X_i\subset \mathbb {P}^n\) , that is each variety \(X_i\) lies in some hyperplane. In particular, we want to determine the dimension and the degree of the Hadamard product of these varieties using the dimensions and the degrees of the varieties \(X_i\) .
