Abstract:
Let L be a line contained in a Grassmannian variety G. A d-rope C ⊂ G sup-
ported on L is a locally Cohen-Macaulay curve of degree d with Cred = L and
(IL,G)2 ⊂ IC,G. We characterize the d-ropes C supported on L and embedded in
G. In some cases we describe also the vector bundles on such a rope C. Finally,
we describe the parameter spaces for ropes embedded in G.
