The Cohen–Macaulay space of twisted cubics
(English)Manuscript (preprint) (Other academic)
In this work, we describe the Cohen-Macaulay space CM of twisted cubics parameterizing curves together with a finite map that is generically a closed immersion and such that has Hilbert polynomial p(t)=3t+1 with respect to . We show that CM is irreducible, smooth and birational to one component of the Hilbert scheme of twisted cubics.
