On the Quaternionic Curves in the Semi-Euclidean Space E^4_2

In this study, we investigate the semi-real quaternionic curves in the semi-Euclidean space E^4_2 . Firstly, we introduce al-gebraic properties of semi-real quaternions. Then, we give some characterizations of semi-real quaternionic involute-evolute curves in the semi-Euclidean space E^4_2 . Finally, we give an example illustrated with Mathematica Programme.
