Herglotz representation

Witrynathe Herglotz representation theorem for these functions. In this connection, we aim to introduce the concept of order of q-starlikeness and prove the Bieberbach conjecture. In particular, we also discuss several other basic properties on the order of q-starlike functions. We now collect some standard notations and basic de nitions used in the ... In mathematics, a positive harmonic function on the unit disc in the complex numbers is characterized as the Poisson integral of a finite positive measure on the circle. This result, the Herglotz-Riesz representation theorem, was proved independently by Gustav Herglotz and Frigyes Riesz in 1911. … Zobacz więcej A positive function f on the unit disk with f(0) = 1 is harmonic if and only if there is a probability measure μ on the unit circle such that The formula … Zobacz więcej • Bochner's theorem Zobacz więcej A holomorphic function f on the unit disk with f(0) = 1 has positive real part if and only if there is a probability measure μ on the unit circle … Zobacz więcej Let $${\displaystyle f(z)=1+a_{1}z+a_{2}z^{2}+\cdots }$$ be a holomorphic function on the unit disk.
