摘要 设T(α,β)表示单位圆盘δ内单叶解析且具有下列形式的函数族(zf')'g'-1/(zf')'g'+(1-2α)<β,这里f(z)=z+1to∞anzn,且g(0)=g'(0)-1=0,本文研究得到了它的系数估计和偏差结论. Let T(α,β) be the class of functionsf(z) = z +∞∑n=2αnz^n analytic in δ,satisfying for some convex function g(z) with g(0) = g' (0) - 1 = 0 and for all z in δ the condition|(zf′)′/(zf′)′+(1-2α)|〈β for some α,β(0≤α〈1,0〈β≤1).A sharp coefficient estimate, distortion theorems are determined for the class T(α,β).
