Resumen de Null helix and k -type null slant helices in E 4 1 .

Jinhua Qian, Young Ho Kim

• We study the null helix and k-type null slant helices in 4-dimensional Minkowski space E41 and characterize them in terms of the null curvature, null torsion and structure functions. Some null helices and k-type null slant helices are presented by solving special differential equations.
