The Caratheodory Inequality on the Boundary for Holomorphic Functions in the Unit Disc
Ornek, B. N. (B VERKIN INST LOW TEMPERATURE PHYSICS & ENGINEERING, 2016)In this paper, a boundary version of the Caratheodory inequality is studied. For the function f(z), defined in the unit disc with f(0) = 0, Rf(z) <= A, we estimate a modulus of angular derivative at the boundary point z(0), ... -
Estimates for Analytic Functions Connected with Hankel Determinant
Ornek, B. N. (Springer, 2022)We give an upper bound of the first-order Hankel determinant (H-2(1)) for the classes of analytic functions. In addition, an estimate with Hankel determinant from below is given for the second angular derivative of an ... -
NOTE ON SOME CLASSES OF HOLOMORPHIC FUNCTIONS RELATED TO JACK'S AND SCHWARZ'S LEMMA
Mateljevic, M.; Mutavdzic, N.; Ornek, B. N. (Univ Belgrade, Fac Electrical Engineering, 2022)In this paper we discuss holomorphic mappings f of the unit disc U and corresponding index defined as I-f (z) = zf'(z)/f(z). We are interested in finding f(z) bounds on the growth of functions f and related issues, if there ...
