We introduce nonwandering operators in infinite-dimensional separable Banach space. They are new linear chaotic operators and are relative to hypercylic operators, but different from them. Firstly, we show some examples for nonwandering operators in some typical infinite-dimensional Banach spaces, including Banach sequence space and physical background space. Then we present some properties of ...

We modify a construction of Kisaka and Shishikura to show that there exists an entire function f which has both a simply connected and a multiply connected wandering domain. Moreover, these domains are contained in the set A(f) consisting of the points where the iterates of f tend to infinity fast. The results answer questions by Rippon and Stallard.

In this paper, we study the problem of wandering continua for a Lattes map. For such a map, we prove that it admits a wandering continuum if and only if it is a flexible Lattes map.

We investigate in which cases the boundary of a multiply connected wandering domain of an entire function is uniformly perfect. We give a general criterion implying that it is not uniformly perfect. This criterion applies in particular to examples of multiply connected wandering domains given by Baker. We also provide examples of infinitely connected wandering domains whose boundary is uniforml...

Subjective inner experiences, such as mind-wandering, represent the fundaments of human cognition. Although the precise function of mind-wandering is still debated, it is increasingly acknowledged to have influence across cognition on processes such as future planning, creative thinking, and problem-solving and even on depressive rumination and other mental health disorders. Recently, there has...

we present observation of polar coronal hole plumes with foot point jets that shows evidence of longitudinal acceleration. the series of event, occurring in the north coronal hole on 10 july 2010, was observed by the aia telescopes of the solar dynamic observatory (sdo mission) in the euv lines, with unprecedented details. the structures along the plume show a propagating outward velocity of ab...

Amajor controversy in cardiac electrophysiology is whether ventricular fibrillation (VF) is maintained by wandering wavelets or mother rotors. On the basis of a computer model of atrial fibrillation by Moe1 developed in 1962, fibrillation was hypothesized to be maintained by multiple small, wandering wavelets, in which the activation pattern is constantly changing. According to the wandering wa...

Ectopy of the spleen also referred to as wandering spleen is a rare condition and preferentially treated by laparoscopic splenopexy. However, in complicated cases with torsion and consecutive infarction of the spleen splenectomy is required. Performing the splenectomy of a wandering spleen laparoscopically has already been reported as a save therapeutic option. However, open splenectomy is usua...
