First, we consider a spacelike curve in the Minkowski space and investigate the Fermi-Walker derivative along the tangent. The concepts with the Fermi-Walker derivative are analyzed along its tangent. Then, the Fermi-Walker derivative and its theorems are analyzed along the principal normal indicatrix and the binormal indicatrix of spacelike curve in .eninfo:eu-repo/semantics/closedAccessFermi-Walker derivativeFermi-Walker parallelismNon-rotating frameTangent indicatrixPrincipal normal indicatrixBinormal indicatrixHelixSlant helixArticle26262564410.1007/s00006-015-0635-92-s2.0-84953308746Q3WOS:000376414600008Q2
