Quasi-position vector curves in Galilean 4-space
A Elsharkawy, N Elsharkawy - Frontiers in Physics, 2024 - frontiersin.org
The Frenet frame is not suitable for describing the behavior of the curve in the Galilean
space since it is not defined everywhere. In this study, an alternative frame, the so-called …

Exploring Hasimoto surfaces within equiform geometry in Minkowski space
A Elsharkawy - Physica Scripta, 2024 - iopscience.iop.org
In this study, we investigate the equiform geometry of Hasimoto surfaces within the context of
three-dimensional Minkowski space. We analyze the geometric characteristics inherent to …
