A note on length distortion for certain classes of analytic functionsShigeyoshi Owa and Shotaro OgawaDepartment of Mathematics, Kinki University HigashiOsaka, Osaka 577, JapanAbstract: Some interesting results on length distortion for certain classes of analytic functions have been proved recently by Y. Komatu. We derive some results involving analytic functions satisfying Re$\{f(z)/z\}>\alpha$, starlike functions of order $\alpha$, and convex functions of order $\alpha$.
