Abstract

This paper is concerned with the new generalized class of tilted analytic univalent functions,  S*(q,a,s,t) which denoted as. Re{ei????f′(z) z }>????, m(z)for cos ???? > ????, |????| < ????, 0 ≤ ???? <1, m(z)= z , s ≠ 1, -1 ≤ t < 1, s ≠ t and s, t ∈ C which is analytic in the unit disk Δ={w:|w|<1}. The (1−sz) (1−tz)coefficient bound as well as representation theorem of extremal properties is obtained S∗(????,????,s,t).
