A notion of positivity, called Seshadri ampleness, is introduced for a smooth curve $C$ in a polarized smooth projective $3$ -fold $(X, A)$ , whose motivation stems from some recent results concerning the gonality of space curves and the behaviour of stable bundles on $P^{3}$ under restriction to $C$ . This condition is stronger than the normality of the normal bundle and more general than $C$ being defined by a regular section of an ample rank- $2$ vector bundle. We then explore some of the properties of Seshadri-ample...
