If F is inner automorphism , what does this mean ?

    hi
    if F is inner automorphism , what does this mean ?

    I think that if
    F : G to G
    then
    we can write F(x) as
    F(x) = g x g^(-1)
    for some fixed g in G and all x in G

    that means that F moves X to the conjgation x by g


    is this right ?

    Yes, I confirmed this on wikipedia.
