On the Hilbert scheme of smooth curves of degree $d=15$ in $\mathbb{P}^5$

Abstract

We denote by $\mathcal{H}_{d,g,r}$ the Hilbert scheme of smooth curves, which is the union of components whose general point corresponds to a smooth irreducible and non-degenerate curve of degree $d$ and genus $g$ in $\mathbb{P}^r$. In this article, we study $\mathcal{H}_{15,g,5}$ for every possible genus $g$ and determine their irreducibility. We also study the birationality of the moduli map up to projective equivalence and several key properties such as gonality of a general element as well as characterizing smooth elements of each component.Comment: Incorrect statement in Remark 3.8 has been corrected.
