Let P N be a projective space over an algebraically closed ΓΏeld of characteristic zero. Let X β P N be a closed, irreducible subvariety, not lying on a hyperplane. The kth higher secant variety of X , denoted X k , is the closure of the union of all linear spaces spanned by k points of X . We prove
