Add to ORKGNew coefficient inequalities for starlike and convex functions MAMORU NUNOKAWA, SHIGEYOSHI OWA, HITOSHI SAITOH, and NORIHIRO TAKAHASHI Abstfact. The object of the present paper is to derive new coefficient inequalities for umivalent and starlike, and univalent and convex functions defined in the open unit disk $U $. Our results are the improvements of the previous theorems given by J. Clunie and F. R. Keogh ([1]) and by H. Silverman ([2]).
