Almost periodic divisors, holomorphic functions, and holomorphic mappings

open access: yesBulletin des Sciences Mathématiques, 2003
We prove that to each almost periodic (in the sense of distributions) divisor in a tube one can assign a first Chern class of a special line bundle over Bohr's compact set generated by the divisor such that the trivial cohomology class represents divisors of all almost periodic holomorphic functions on a tube.

Some properties of a class of holomorphic functions associated with tangent function

open access: yesDemonstratio Mathematica
In this study, we define new class of holomorphic functions associated with tangent function. Furthermore, we examine the differential subordination implementation results related to Janowski and tangent functions. Also, we investigate some extreme point

Symmetric representations of holomorphic functions

open access: yesIssues of Analysis, 2018
In this article a class of symmetric functions is defined and used in some special representation of holomorphic functions. This representation plays an important role in transitions from concrete problems of projective description to equivalent problems of inductive description and finds multiple applications in questions connected with spectral ...

Holomorphic functions on subsets of ${\Bbb C}$

open access: yesJournal of the Mathematical Society of Japan, 2013
Let $ $ be a $C^\infty $ curve in $\Bbb{C}$ containing 0; it becomes $ _ $ after rotation by angle $ $ about 0. Suppose a $C^\infty $ function $f$ can be extended holomorphically to a neighborhood of each element of the family $\{ _ \}$. We prove that under some conditions on $ $ the function $f$ is necessarily holomorphic in a neighborhood of ...

ELEMENTARY SOLUTIONS OF A HOMOGENEOUS Q-SIDED CONVOLUTION EQUATION

open access: yesПроблемы анализа, 2018
Spectral synthesis on the complex plane related to solutions of some homogeneous equations of convolution type. There is a method to obtain solutions: we describe the elementary solutions set of the equation (spectral analysis) and prove the ...

Multiply Universal Holomorphic Functions

open access: yesJournal of Approximation Theory, 1997
AbstractLet O⊂C, O≠C, be an open set with simply connected components. In Theorem 1 we prove the existence of a holomorphic functionφon O, which has together with all its derivatives and all its antiderivatives six universal properties at the same time (based on the behaviour of sequences of derivatives or antiderivatives, overconvergence-phenomena, or
