Can the cross product of threedimensional vectors be generalized to
relativistic 4 - vectors ? What does mathematics say ?

Why not? However it may not be physically meaningful.
I suspect (but don't know) that the answer is already there, buried in
tensor analysis.

Why not meaningful ? Maybe there is something which is meaninful ? Thats my
question.
