We use Bowen's definition of topological entropy and Ahlfors five islands theorem, as well as the theory of polynomial-like mappings, to show that the topological entropy of any entire transcendental function is infinity. In addition the entropy is concentrated on the Julia set for each meromorphic function which has no wandering domains.
We prove that there exist three transcendental entire functions that have infinite number of domains which lie in the wandering component of each of these functions and their composites. This result is a generalization of the result of Dinesh Kumar, Gopal Datt and Sanjay Kumar. In particular, they proved that there exist two transcendental entire functions that have infinite number of domains which lie in the wandering components of each of these functions and their composites.
Baker proved that for transcendental entire functions there is at most one completely invariant component of the Fatou set. It was observed by Julien Duval that there is a missing case in Baker's proof. In this article we follow Baker's ideas and give some alternative arguments to establish the result.

We prove that entire transcendental holomorphic functions with an omitted value have infinite entropy. A proof for general transcendental entire functions will be given in an upcoming paper.
Let $f$ be a map with bounded set of singular values for which periodic dynamic rays exist and land. We prove that each non-repelling cycle is associated to a singular orbit which cannot accumulate on any other non-repelling cycle. When $f$ has finitely many singular values this implies a refinement of the Fatou-Shishikura inequality. Our approach is combinatorial in the spirit of the approach used by [Ki00], [BCL+16] for polynomials.

We identify a class of hyperbolic transcendental entire maps and we prove that some of its elements generate a class of potentials for which exhibit a conformal and invariant probability Gibbs measure. The methods and techniques from the thermodynamic formalism can be extended to this class of potentials. To complement this study we highlight that the dynamics of such a map on some subset of the Julia set is conjugated to the shift map over a code space with countable alphabet and the euclidean metric on the complex plane induces a metric on the symbolic space which is not compatible with the …
In this paper, we have investigated the Bungee set of composition of two transcendental entire functions. We have provided a class of permutable entire functions for which their Bungee sets are equal. Moreover, we have obtained a result on permutable entire functions for which the escaping set of the composite entire function equals the union of the escaping sets of the two functions. In addition, we establish important relations between the Bungee set, Escaping set and Filled Julia set of composite entire functions with that of its individual functions.
Very little is currently known about the dynamics of non-polynomial entire maps in several complex variables. The family of transcendental Hénon maps offers the potential of combining ideas from transcendental dynamics in one variable, and the dynamics of polynomial Hénon maps in two. Here we show that these maps all have infinite topological and measure theoretic entropy. The proof also implies the existence of infinitely many periodic orbits of any order greater than two.

Non-landing hairs in Sierpinski curve Julia sets of transcendental entire maps
本文考虑由$f_a(z)=a(z-(1-a))\exp(z+a)$给出的超越整映射族,其中$a$是复参数.每个映射在$z=-a$有一个超吸引不动点,在$z=0$有一个渐近值。对于$a>1$,已知$f_a$的Julia集同胚于Sierpienski通用曲线,因此包含任何一维平面连续体的嵌入副本。在本文中,我们研究的Julia集,可以定义在一个组合的方式下的子连续统。特别是,我们表明存在的非着陆头发与规定的组合嵌入在朱莉娅集的所有参数$a\geq 3$。我们还研究了非着陆毛与$z=-a$的直接吸引区域之间的关系。即使每一个非着陆的头发在一个点上积累到直接盆地的边界上,它的闭包仍然成为Julia集的不可分解的子连续统。

本文研究了一类映射的周期点的分布,即具有有界奇异值集的有穷级整超越函数或其组合。修复$p\in\N$,并假设所有在$f^p$下不变的动态光线都是陆地。内部$p$ -周期点是$f^p$的不动点,它不是在$f^p$下不变量的任何周期射线的着陆点。属于吸引、西格尔或克里默循环的点是内部周期点的例子。对于上述功能,我们表明,射线是不变的下$f^p$,连同他们的着陆点,分离的平面成100多个区域,每一个恰好包含一个内部$p-$周期点或一个抛物线立即盆不变下$f^p$。这个结果推广了多项式的Goldberg-Milnor分离定理,并有几个推论。例如,两个周期性Fatou分量总是可以被一对同时入射的周期性射线分开; Siegel圆盘的边界上不可能有Cremer点;有界Siegel圆盘的“隐藏分量”要么是游荡域,要么是Siegel圆盘本身的预周期;或者,无论奇异值的数量如何,在任何给定的周期中,只有100多个非排斥循环。
The notion of nearly abelian rational semigroup was introduced by Hinkannen and Martin. In this paper, we have introduced the notion of nearly abelian transcendental semigroup. We have extended the results of nearly abelian rational semigroups to the best possible class of nearly abelian transcendental semigroups. We have given a class of functions which nearly permute with a given transcendental entire function. In addition, a relation between the postsingular set of composition of two entire functions with that of individual functions is obtained.

The escaping set in transcendental dynamics

We consider transcendental entire functions that are compositions of a polynomial and the exponential for which all singular values escape on disjoint rays. Based on their classification in [B3] we investigate their dependence on parameters, that is, on the potentials and external addresses of singular values. Using continuity argument we generalize the classification in [B3] to the case when dynamic rays containing singular values are (pre-)periodic.
A generalized family of transcendental (non-polynomial entire) functions is constructed, where the Hausdorff dimension and the packing dimension of the Julia sets are equal to one. Further, there exist multiply connected wandering domains, the dynamics can be completed described, and for any $s\in(0,+\infty]$, there is a function taken from this family with the order of growth $s$. Baker proved that the Hausdorff dimension of the transcendental function is no less than one in 1975, the minimum value was obtained via an elegant construction by Bishop in 2018. The order of growth is zero in Bish…

We study the parameter planes of certain one-dimensional, dynamically-defined slices of holomorphic families of entire and meromorphic transcendental maps of finite type. Our planes are defined by constraining the orbits of all but one of the singular values, and leaving free one asymptotic value. We study the structure of the regions of parameters, which we call {\em shell components}, for which the free asymptotic value tends to an attracting cycle of non-constant multiplier. The exponential and the tangent families are examples that have been studied in detail, and the hyperbolic components…
Rigidity of escaping dynamics for transcendental entire functions
本文证明了B类中超越整函数的Boettcher定理的一个类似定理。更准确地说,设f和g是具有有界奇异值集的整函数,并假设f和g属于相同的参数空间(即,在Eremenko和Lyubich的意义上是 * 拟共形等价的 *)。然后f和g是共轭时,限制到一组点仍然在一些足够小的邻域无穷迭代。此外,这种共轭性推广到平面的拟共形自映射。我们还证明了这种共轭性本质上是唯一的。特别是,我们证明了Eremenko-Lyubich类函数f在其逃逸集上没有不变的线场。最后证明了属于同一参数空间的任意两个双曲Eremenko-Lyubich类函数f和g在其逃逸点集上共轭。
This paper discusses iterated monodromy groups for transcendental functions. We show that for every post-singularly finite entire transcendental function, the iterated monodromy action can be described by bounded activity automata of a special form, called "dendroid automata". In particular, we conclude that the iterated monodromy group of a post-singularly finite entire function is amenable if and only if the monodromy group is.
In recent years, there has been significant progress in the understanding of the dynamics of transcendental entire functions with bounded postsingular set. In particular, for certain classes of such functions, a complete description of their topological dynamics in terms of a simpler model has been given inspired by methods from polynomial dynamics. In this paper, and for the first time, we give analogous results in cases when the postsingular set is unbounded. More specifically, we show that if $f$ is of finite order, has bounded criticality on its Julia set $J(f)$, and its singular set consi…
Brushing the hairs of transcendental entire functions
设f是Eremenko-Lyubich类中的有穷级双曲超越整函数(或这类映射的有限复合),且f有唯一的Fatou分支.我们表明,朱利亚集的$f$是康托花束,即环境同胚的直刷的意义上的Aarts和Oversteegen。特别地,我们证明了任意两个这样的朱利亚集是环境同胚的.我们还表明,如果$f\in\B$有有穷级(或是一个有限的组成,这样的地图),但不一定是双曲的,那么朱利亚集的f包含一个康托花束。作为我们的证明的一部分,我们描述,为任意函数$f\in\B$,一个自然的紧化的动态平面通过添加一个“圆的地址”在无穷大。

Inner functions associated to lifts of transcendental entire functions
本文提出一种通用方法,将一类作为“提升”的整函数的内函数计算归结为被提升函数的内函数计算,推广了Evdoridou、Rempe和Sixmith的主要定理。
The issue of whether an analytic function has wandering domains has long been of interest in complex dynamics. Sullivan proved in 1985 that rational maps do not have wandering domains. On the other hand, several transcendental entire functions have wandering domains. Using recent results on the relationship between Fatou components and the postsingular set, we find a new family of transcendental entire functions that does not have wandering domains. We also prove that the Julia set of a certain subfamily is the whole plane.
Functions of small growth with no unbounded Fatou components
证明了$\cos πρ$定理的一种形式,该定理给出了零阶超越整函数的最小模的强估计。我们还证明了Hinkkanen的一个结果的推广,给出了一个充分条件的超越整函数没有无界Fatou组件。这两个结果使我们能够证明,有一大类零阶整函数没有无界Fatou分量。另一方面,我们给出的例子表明,实际上有功能的零阶不仅不满足Hinkkanen的条件,但也不满足我们更一般的条件。我们还给出了一个新的正则性条件,该条件足以保证一个小于1/2阶的超越整函数没有无界的Fatou分量。最后,我们观察到,这里给出的所有条件,保证了一个超越整函数没有无界Fatou组件,也保证了逃逸集是连接的,从而回答了一个问题,Eremenko为这样的功能。
We provide the full theory of thermodynamic formalism for a very general collection of entire functions in class $\mathcal B$. This class overlaps with the collection of all entire functions for which thermodynamic formalism has been so far established and contains many new functions. The key point is that we introduce an integral means spectrum for logarithmic tracts which takes care of the fractal behavior of the boundary of the tract near infinity. It turns out that this spectrum behaves well as soon as the tracts have some sufficiently nice geometry which, for example, is the case for quas…

We construct a family of transcendental entire functions whose Julia sets have packing dimension in $(1,2)$. These are the first examples where the computed packing dimension is not $1$ or $2$. Our construction will allow us further show that the set of packing dimensions attained is dense in the interval $(1,2)$, and that the Hausdorff dimension of the Julia sets can be made arbitrarily close to the corresponding packing dimension.
Random Dynamics of Transcendental Functions
本文研究了有穷级双曲整函数和亚纯函数的随机动力学,其导数在无穷远处满足一定的增长条件。这个类包含了大多数经典的超越函数族,并且远远超出了它。基于Nevanlinna的值分布理论的统一版本,我们首先建立了一个数学形式主义,特别是,产生独特的几何和纤维不变的吉布斯态。此外,谱间隙性质的相关性的指数衰减和中心极限定理的相关转移算子。这一部分依赖于我们的建设新的积极不变锥,适应于无界相空间的设置。这种设置排除了希尔伯特度量和通常的压缩原理的使用。然而,这些锥体使我们能够应用源于Bowen最初方法的收缩论点。
A transcendental entire function is called criniferous if every point in its escaping set can eventually be connected to infinity by a curve of escaping points. Many transcendental entire functions with bounded singular set have this property, and this class has recently attracted much attention in complex dynamics. In the presence of escaping critical values, these curves break or split at (preimages of) critical points. In this paper, we develop combinatorial tools that allow us to provide a complete description of the escaping set of any criniferous function without asymptotic values on its…
