Herglotz representation
WitrynaThe proof relies on the Herglotz representation for non-negative harmonic functions on the upper half-plane; Herglotz' representation is fundamental to a large body of holomorphic and harmonic function theory on the unit disk and in the half plane. In it's most general form, the Herglotz representation holds for all non-negative harmonic ... WitrynaHerglotz [3], there is for each h E Ofo a unique representing measure vh on C, ; that is, h(a)=f P(z,a)dvh(z) 'c, for each a E D. Moreover, vh is the weak* limit as r -» 1 of the measures hXr on Cr. Note that vh is both a measure on C, and on the harmonic functions [P(z, •): z E Cx); these functions are the extreme points in the convex set x0

WitrynaAbstract. For every q∈ (0,1) q ∈ ( 0, 1) and 0 ≤ α< 1 0 ≤ α < 1 we define a class of analytic functions, the so-called q q -starlike functions of order α α, on the open unit disk. We study this class of functions and explore some inclusion properties with the well-known class of starlike functions of order α α.

Comparing to the implicit representation formula in [], an advantage of Herglotz’ variational principle is that one can obtain various kinds of representation formulas by choosing different ways to solve 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.
