We classify the twisted surface with respect to their spine curve which are non -null or null curves. So, we study the geometric properties of these surfaces. Also we obtain the family of some special surfaces such as flat surfaces, marginally trapped surfaces.eninfo:eu-repo/semantics/openAccessTwisted surface; normal curvature tensor; parallel mean curvature vector; minimal surface; flat surfaceTwisted Surfaces in Semi-Euclidean 4-Space with Index 2Article171243310.36890/IEJG.14043662-s2.0-85191393689Q4WOS:001313799400003N/A
