M.MahmoudDepartment of Mathematics Aswan University Faculty of Science Aswan, EGYPTAlaa HassanNoreldeenDepartment of Mathematics Aswan University Faculty of Science Aswan, EGYPTIn this paper, we study inextensible flows of spacelike curves lying fully on a spacelike surface Ω according to equiform frame in 4-dimensional Minkowski space ℝ1 4 . We give necessary and sufficient conditions for this inextensible flows which are expressed as a partial differential equation involving the equiform curvature functions in 4-dimensional Minkowski space ℝ1 4 . Finally we give an application of inextensible flows of spacelike curves in ℝ1 4 .21020212102021683698https://www.wseas.org/multimedia/journals/mathematics/2020/b525106-1359.pdf10.37394/23206.2020.19.75https://www.wseas.org/multimedia/journals/mathematics/2020/b525106-1359.pdf10.4310/jdg/1214448076S.
