Abstract

We consider generic degenerate subvarieties X_i⊂ℙⁿ. We determine an integer N, depending on the varieties, and for n≥ N we compute dimension and degree formulas for the Hadamard product of the varieties X_i. Moreover, if the varieties X_i are smooth, their Hadamard product is smooth too. For n
