Zalcman引理在随机迭代函数族动力系统中的应用

本文根据Schwick的思想,利用Zalcman引理讨论了随机迭代函数族动力系统,指出了函数族随机迭代动力系统的Fatou集和函数族衍生半群动力系统的Fatou集定义差别明显但却等价.并获得了如下正规定则,设F={f_i|f_i为C（C）上的非线性解析函数,i ∈ M},其中M为非空指标集,Σ_M={（j₁,j₂,…,j_n,…）|j_i ∈ M,i ∈ N},若对任意的指标序列σ=（j₁,j₂,…,j_n,…）∈ Σ_M,迭代序列{W_σⁿ=f_jn º f_jn-1 º … ºf_j1（z）|n ∈ N}在点z处正规,则函数族F本身在点z处正规.     

Bicomplex hyperfunctions

In this paper, we consider bicomplex holomorphic functions of several variables in _boxclose C^n{{\mathbb B}{\mathbb C}^n} .We use the sheaf of these functions to define and study hyperfunctions as their relative 3n-cohomology classes. We show that such hyperfunctions are supported by the Euclidean space \mathbb Rⁿ{{\mathbb R}^n} within the bicomplex space \mathbb B\mathbb Cⁿ{{\mathbb B}{\mathbb C}^n}, and we construct an abstract Dolbeault complex that provides a fine resolution for the sheaves of bicomplex holomorphic functions. As a corollary, we show how that the bicomplex hyperfunctions can be represented as classes of differential forms of degree 3n − 1.     

Topological Bicomplex Modules

In this paper, we develop topological modules over the ring of bicomplex numbers. We discuss bicomplex convexity, hyperbolic-valued seminorms and hyperbolic-valued Minkowski functionals in bicomplex modules. We also study the conditions under which topological bicomplex modules and locally bicomplex convex modules become hyperbolic normable and hyperbolic metrizable respectively.     

Finite-Dimensional Bicomplex Hilbert Spaces

This paper is a detailed study of finite-dimensional modules defined on bicomplex numbers. A number of results are proved on bicomplex square matrices, linear operators, orthogonal bases, self-adjoint operators and Hilbert spaces, including the spectral decomposition theorem. Applications to concepts relevant to quantum mechanics, like the evolution operator, are pointed out.     

Infinite Dimensional Bicomplex Spectral Decomposition Theorem

This paper presents a bicomplex version of the Spectral Decomposition Theorem on infinite dimensional bicomplex Hilbert spaces. In the process, the ideas of bounded linear operators, orthogonal complements and compact operators on bicomplex Hilbert spaces are introduced and treated in relation with the classical Hilbert space M′ imbedded in any bicomplex Hilbert space M.     

Complex Laplacian and Derivatives of Bicomplex Functions

In this paper we study in detail the theory of bicomplex holomorphy, in the context of the several ways in which bicomplex numbers can be considered. In particular we will show how the notions of bicomplex derivability and bicomplex holomorphy can be interpreted in these different ways, and the consequences that can be derived.     

Homothetic Motions at E 4 with Bicomplex Numbers

In this paper, a matrix which is similar to Hamilton operators has been presented to bicomplex numbers in four dimensional Euclidean space E ⁴. We show that if the matrix is obtained from a curve on the Lie group M, then the motion is a homothetic motion. It has been found that the motion defined by a regular curve of order r and derivations curves on the hypersurface M has only one acceleration center of order (r - 1) at every t-instant.     

Blow-up Lemma

Regular pairs behave like complete bipartite graphs from the point of view of bounded degree subgraphs.     

Weight Lemma

In the paper, we give the first complete presentation of author’s proof of the Weight Lemma, which lies at the basis of the proof of Cartan’s conjecture from the theory of meromorphic curves.__________Translated from Matematicheskie Zametki, vol. 78, no. 1, 2005, pp. 115–124.Original Russian Text Copyright © 2005 by E.

On Lelong-Bremermann Lemma

The main theorem of this note is the following refinement of the well-known Lelong-Bremermann Lemma:

Let be a continuous plurisubharmonic function on a Stein manifold of dimension Then there exists an integer , natural numbers , and analytic mappings such that the sequence of functions

converges to uniformly on each compact subset of .

In the case when is a domain in the complex plane, it is shown that one can take in the theorem above (Section 3); on the other hand, for -circular plurisubharmonic functions in the statement of this theorem is true with (Section 4). The last section contains some remarks and open questions.

     

Bicomplex Weighted Hardy Spaces and Bicomplex <Emphasis Type="Italic">C</Emphasis>*-algebras

In this paper we study the bicomplex version of weighted Hardy spaces. Further, we describe reproducing kernels for the bicomplex weighted Hardy spaces. In particular, we generalize some results which holds for the classical weighted Hardy spaces. We also introduce the notion of bicomplex C*-algebra and discuss some of its properties.     

A uniqueness theorem and the myrberg phenomenon for a Zalcman domain

LetR=Δ₀\∪_nΔ_n be a Zalcman domain (or L-domain), where Δ₀ : 0<|z| <1, Δ_n : |z-c _n|≤r _n,c_n ↘0, Δ_n ⊂ Δ₀ and Δ_n ∩ Δ_m= φ(n≠m). 0217 0115 V 3 For an unlimited two-sheeted covering with the branch points {φ^-1(c _n)}, set . In the casec _n=2⁻ⁿ , it was proved that if a uniqueness theorem is valid forH ^∞ (R) atz=0, then the Myrberg phenomenon occurs. One might suspect that the converse also holds. In this paper, contrary to this intuition, we show that the converse of this previous result is not true. In addition, we generalize the previous result for more general sequences {c _n}. By this generalization we can even partly simplify the previous proof.

Multicolor Combination Lemma

We present an extension of the Combination Lemma of Guibas et al. (1983) that expresses the complexity of one or several faces in the overlay of many arrangements (as opposed to just two arrangements in (Guibas et al. 1989)), as a function of the number of arrangements, the number of faces, and the complexities of these faces in the separate arrangements. Several applications of the new Combination Lemma are presented. We first show that the complexity of a single face in an arrangement of k simple polygons with a total of n sides is Θ(n(k)), where (·) is the inverse of Ackermann's function. We also give a new and simpler proof of the bound on the total number of edges of m faces in an arrangement of n Jordan arcs, each pair of which intersect in at most s points, where λ_s(n) is the maximum length of a Davenport–Schinzel sequence of order s with n symbols. We extend this result, showing that the total number of edges of m faces in a sparse arrangement of n Jordan arcs is , where w is the total complexity of the arrangement. Several other related results are also obtained.

The Non-Commutative Cycle Lemma

We present a non-commutative version of the Cycle Lemma of Dvoretsky and Motzkin that applies to free groups and use this result to solve a number of problems involving cyclic reduction in the free group. We also describe an application to random matrices, in particular the fluctuations of Kesten's Law.
