An interpolation problem for the normal bundle of curves of genus $g\ge 2$ and high degree in ${\mathbb{P}}^r$

Abstract

Let $C\subset {\mathbb{P}}^n$ be a smooth curve and $N_C$ its normal bundle. $N_C$ satisfies strong interpolation if for all integers $s>0$ and ${\lambda }_i\in \{0,1,\dots ,n-1\}$, $1\le i\le s$, there are distinct points $P_1,\dots ,P_s\in C$ and linear subspaces $U_i\subseteq E|P_i$ such that $\dim (U_i)={\lambda }_i$ for all $i$ and the evaluation map $H^0(E)\to {\oplus }_{i=1}^s{U}_i$ has maximal rank (A. Atanasios). We prove that $C$ satisfies strong interpolation if either $C$ is a linearly normal elliptic curve or $C$ is a general embedding of degree $d\ge (5n-8)g+2n^2-5n+4$ of a smooth curve $X$ of genus $g\ge 2$.
