Özet
The aim of this study is to solve the Fekete-Szego problem and to define upper bound for Hankel determinant H-2(1) in a novel class K of analytical functions in the unit disc. Moreover, in a class of analytic functions on the unit disc, assuming the existence of an angular limit on the boundary point, the estimations from below of the modulus of angular derivative have been obtained.
