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. إقراء المزيد
