Constant ratio curves according to parallel transport frame in euclidean 4-space e^4

In this study, we consider a regular curve in Euclidean 4-space E^4 whose position vector is written as a linear combination of its parallel transport frame vectors. We characterize constant ratio curves in terms of their curvature functions. Further, we obtain some results of T-constant type and N-constant type curves according to its Bishop curvatures in E^4.
