## Abstract

Let the function f be analytic in zD z : z 1 and be given by 2 n . n n f z z az For 0 1, denote by V and U , the sets of functions analytic in D, satisfying '' Re 1 ' 1 0 ' zf z f z f z and ' Re 1 0 f z zf z z fz respectively, so that f V zf 'U . We give sharp bounds for the Hankel determinant 2 2 2 4 3 H a a a for f V and f U .
