The Clairaut's theorem on rotational surfaces in pseudo Euclidean 4-space with index 2

In this paper, Clairaut's theorem is expressed on the surfaces of rotation in semi Euclidean 4-space. Moreover, the general equations of time-like geodesic curves are characterized according to the results of Clairaut's theorem on the hyperbolic surfaces of rotation and the elliptic surface of rotation respectively.Comment: 13 pages, no figures. arXiv admin note: text overlap with arXiv:2107.1337
