Abstract: Let F be a field of characteristic not 2 and 3.Let f: Mmn(F)→Mmn(F) be an additive map preserving {1,2,T}-inverse, i.e. f(A)=f(A)f(B)Tf(A), f(B)= f(B)f(A)Tf(B) for any A,B∈Mmn(F) with A=ABTA, B=BATB. In this paper, we give the sufficient and necessary condition for f to be such a map.

Key words: additive map, preserving {1, 2, T}-inverse
