Generalization of general helices and slant helices

In this work, we use the formal definition of $k$-slant helix cite{ali2} to obtain the intrinsic equations as well as the position vector for emph{slant-slant helices} which a generalization of emph{general helices} and emph{slant helices}. Also, we present some characterizations theorems for $k$-slant helices and derived, in general form, the intrinsic equations for such curves. Thereafter, fr...

Determination of time-like helices from intrinsic equations in Minkowski 3-Space

In this paper, position vectors of a time-like curve with respect to standard frame of Minkowski space E31 are studied in terms of Frenet equations. First, we prove that position vector of every time-like space curve in Minkowski space E31 satisfies a vector differential equation of fourth order. The general solution of mentioned vector differential equation has not yet been found. By special c...

A ug 2 00 9 Position vectors of a spacelike general helices in Minkowski Space

In this paper, position vector of a spacelike general helix with respect to standard frame in Minkowski space E 1 are studied in terms of Frenet equations. First, a vector differential equation of third order is constructed to determine position vector of an arbitrary spacelike general helix. In terms of solution, we determine the parametric representation of the general helices from the intrin...

9 Position vectors of slant helices in Euclidean space E 3

In classical differential geometry, the problem of the determination of the position vector of an arbitrary space curve according to the intrinsic equations κ = κ(s) and τ = τ (s) (where κ and τ are the curvature and torsion of the space curve ψ, respectively) is still open [7, 14]. However, in the case of a plane curve, helix and general helix, this problem is solved. In this paper, we solved ...
