Abstract :Let P insert ignore into journalissuearticles values(Ş); be the class of funetions u given by u insert ignore into journalissuearticles values(z); = l-fCiZ + c2z24--.- regular in D — ^z: |z | < 1J and satisfying the condition Re insert ignore into journalissuearticles values(z);} > Ş, z e D, 0 < p < 1. Let S*insert ignore into journalissuearticles values(a); and S insert ignore into journalissuearticles values(m,M); be the class of funetions f given by f insert ignore into journalissuearticles values(z); = z4-a„z2-j-... regular in D and satisfying the condition
