Bipolynomial Hilbert functions
E. Carlini, M. V. Catalisano, A. V. Geramita
Let X be a closed subscheme and let HF(X,-) and hp(X,-) denote, respectively, the Hilbert function and the Hilbert polynomial of X. We say that X has bipolynomial Hilbert function…

Secant Varieties of Grasmann Varieties
M. V. Catalisano, A. V. Geramita, A. Gimigliano
In this paper we discuss the dimensions of the (higher) secant varieties to the Grassmann varieties, embedded via the Plucker embeddings. We use Terracini's Lemma and the duality i…
