Geometric characterization of pointwise slant curves.

In the present paper we study the characteristics of pointwise slant curves in a normal almost contact semi-Riemannian three-manifold N3. These curves are characterized by the pseudo-Riemannian scalar product between the normal vector at the curve and the reeb vector field of manifold N3. In this class of manifolds, curvature and torsion of such curves are determined. The Lancret of slant curves in manifold N3 is obtained. Additionally, pointwise slant curves with proper mean curvature are characterized. [ABSTRACT FROM AUTHOR]
