Characterizations of Frenet curves in Galilean 3-space
Abstract
The aim of this paper is to prove that the distance function of every Frenet curve in G3 satisfies a 4-th order differential equation. Also, we show that if α is a unit speed Frenet curve in G3, then <α(s),T(s)>=s+c if and only if α is a rectifying curve. Finally, we obtain some characterizations of spherical curves and helices via the 4-th order differential equation (4).
