Optical effects of some motion equations on quasi-frame with compatible Hasimoto map

Optik, 2021
Abstract In this study, we examine the relationship between some equations of motion and the equations obtained by considering the differential formula of the quasi-Hasimoto map and some physical issues. Here, we first obtain the necessary equations of the quasi-Hasimoto transformation as the quasi-frame equivalent of the Hasimoto map.

Directional Inextensible Flows of Curves by Quasi Frame

Journal of Advanced Physics, 2018
In this paper, we construct a new method for directional inextensible flows of curves using the q-frame. With this new concept, we derive the necessary and sufficient condition for the given curve to be the inextensible flow. Moreover, we give some new characterizations for curvatures of a curve. Finally, we obtain new relations of q-frame in space.

Evolutions of the Ruled Surfaces via the Evolution of Their Directrix Using Quasi Frame along a Space Curve

open access: yesJournal of Applied Mathematics and Physics, 2018
In this paper, evolutions of ruled surfaces generated by the quasi normal and quasi binormal vector fields of space curve are presented. These evolutions of the ruled surfaces depend on the evolutions of their directrix using quasi frame along a space curve.
