We also prove that any complex split quaternion has a 4 x 4 complex matrix representation. On the other hand, we give answers to the following two basic questions If AB = I, is it true that BA = I for complex split quaternion matrices? and How can the inverse of a complex split quaternion matrix be found?. Finally, we give an explicit formula for the inverse of a complex split quaternion matrix by using complex matrices.eninfo:eu-repo/semantics/closedAccess[Keyword Not Available]Article2336256382-s2.0-84881373506Q3WOS:000323070100008Q410.1007/s00006-013-0399-z
