V. AB-ABAB = A[A,B]B, AB-ABA = A[A,B]. Taking Transposes, (neglecting signs..) B[A,B]A, [A,B]A which says K([A,B]A) in K(B[A,B]A) Now noting A[A,B][A,B]A = A{AB[A,B]A -BA{AB-BA}A} = A{AB[A,B]A} = A{B[A,B]A}, which tells me the other part. VI. I rather assume E & G are symmetric. Then using variational principle, it's easy to show that F should be null. -- 난 네가 분노를 느끼기를 바래... |
