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