Study on Universally Prestarlike Functions of Complex Order

Ruscheweyh recently introduced universally prestarlike functions of order (alpha)(le)1 in the slit domain (Lambda) = (mathitC)[1,(infty)) in the slit domain. This concept is a generalisation of the one for functions in the unit disc (Delta) ( and other circular domains in C). We introduce universally prestarlike complex order functions in this study. The Fekete-Szegö inequality…
