چکیده

Let a be a banach algebra with unity 1, and theta; : a rarr; a be an continuous automorphism. in this paper we characterizea continuous linear map t : a rarr; a which satisfies one of the following conditions:a, b isin; a, ab = w = rarr; theta;(a)t(b) = t(w),a, b isin; a, ab = w = rarr; t(a) theta;(b) = t(w),or a, b isin; a, ab = w = rarr; theta;(a)t(b) = t(a) theta;(b) = t(w) , where w ne; 0 is a left (right) separating point of a.
