“…Particularly, if C is parameterized by the arc-length, the magnetic curve C is called a normal curve. For a contact Lorentzian manifold, if (M × R, J, G) belongs to the class W 4 [22], a trans-Sasakian structure [23] is an almost contact metric structure (φ α , ξ α , η α , g) on M, where J is an almost complex structure on M × R [1,[24][25][26], defined by…”
