Abstract
If X⊂Pn is a reduced and irreducible projective variety, it is interesting to find the equations describing the (higher) secant varieties of X. In this paper we find those equations in the following cases:•X=Pn1×⋯×Pnt×Pn is the Segre embedding of the product and n is “large” with respect to the ni (Theorem 2.4);•the X are some “unbalanced” Segre–Veronese embeddings;•X is a Del Pezzo surface.
