A generalization of the notion of helix

Abstract: In this paper we generalize the notion of helix in the three-dimensional Euclidean space, which we define as that curve $C$ for which there is an $F$-constant vector field $W$ along $C$ that forms a constant angle with a fixed direction $V$ (called an axis of the helix). We find the natural equation and the geometric integration of helices $C$ where the $F$-constant vector field $W$ is orthogonal to its axis.
