Serret-frenet formulas for octonionic curves
(Soc Paranaense Matematica, 2020)
In this paper, we define spatial octonionic curves (SOC) in R( )(7)and octonionic curves (OC) in R-8 by using octonions. Firstly, we determine Serret-Frenet equations, and curvatures of the SOC in R-7. Then, Serret-Frenet ...
