Let?? be the class of functionsf(z)=z+?_(n=2)^8¦?a_n z^n ?analytic in the unit discE={z:|z|<1}. Let S(a) denote the class of functions in ?? satisfying the condition Re{((1-a)zf^' (z))/(f(z)-f(-z) )+?a(zf^' (z) )?^'/(f(z)-f(-z) )^' }> 0,(0=a=1)and z?E. We are interested in determining the upper bounds of the FeketeSzego ¨ functional |a_3-µa_2^2 | for functions of the class S(a). MATHEMATICS SUBJECT CLASSIFICATION:30C45
