Curvilinear subschemes of Segre varieties and the cactus rank
Main Article Content
Abstract
We study zero-dimensional linearly dependent subschemes W of the Segre variety with deg(W)≤5. If W is connected and curvilinear with arbitrary degree we give a strong restriction on the number of factors of the concise Segre containing W.
