| Abstract: | In this note the image domain of the complex dilatation of an extremal quasi conformal mapping which maps unit disk onto itself is studied. Under some additional conditions, a necessary and sufficient condition for an extremal dilatation is obtained. As a special case, M.Ortel and W. Smith's result in 1988 is improved. |
