Abstract. We start the discussion of the following query. Let be an integral and non-degenerate curve. For each let (resp. , resp. ) be the minimal degree of a zero-dimensional (resp. zero-dimensional and connected, resp. zero-dimensional connected and curvilinear) scheme such that , where denote the linear span. Compute the maximal integer and when is arbitrary (resp. general) in .
