چکیده	Let A be a factor von Neumann algebra, with unit I, which contains a nontrivial projection P1, and let : A ! A be a surjective map that satis es one of the two conditions: (A) (P) +  (P) (A) = AP + PA and (A) (P) +  (P) (A) = AP + PA for all A 2 A and P 2 fP1; I 􀀀 P1g and  2 f􀀀1; 1g. Then, we determine the concrete form of .
