Inextensible flows of curves in three-dimensional light cone
In this paper, we study inextensible flows of spacelike and lightlike (null) curves in 3- dimensional light cone Q3 of Minkowiski 4-space E4 1 . We introduce the necessary and sufficient conditions for inextensible flows of these curves which can be expressed as partial differential equations involving the curvatures. Read more

SOME PROPERTIES OF SPECIAL MAGNETIC CURVES
In the theory of curves, a magnetic field generates a magnetic flow whose trajectories are curves called magnetic curves. This paper aims at studying some properties for these curves which corresponding to the Killing magnetic fields in the 3-dimensional Euclidean space. We investigate the trajectories of the magnetic fields called T-magnetic and e-magnetic curves, also we give some characterizations of ... Read more
