Common Fixed Point Theorems for Totally Quasi-G-Asymptotically Nonexpansive Semigroups with the Generalized f-Projection  [PDF]
Chunjie Wang, Yuanheng Wang
Applied Mathematics (AM) , 2014, DOI: 10.4236/am.2014.51004
Abstract:

In this paper, we introduce some new classes of the totally quasi-G-asymptotically nonexpansive mappings and the totally quasi-G-asymptotically nonexpansive semigroups. Then, with the generalized f-projection operator, we prove some strong convergence theorems of a new modified Halpern type hybrid iterative algorithm for the totally quasi-G-asymptotically nonexpansive semigroups in Banach space. The results presented in this paper extend and improve some corresponding ones by many others.

Strong Convergence Theorems for Asymptotically Weak -Pseudo--Contractive Non-Self-Mappings with the Generalized Projection in Banach Spaces
Yuanheng Wang
Abstract and Applied Analysis , 2012, DOI: 10.1155/2012/651304
Abstract: A new concept of the asymptotically weak -pseudo--contractive non-self-mapping is introduced and some strong convergence theorems for the mapping are proved by using the generalized projection method combined with the modified successive approximation method or with the modified Mann iterative sequence method in a uniformly and smooth Banach space. The proof methods are also different from some past common methods.
Strong Convergence of the Iterative Methods for Hierarchical Fixed Point Problems of an Infinite Family of Strictly Nonself Pseudocontractions
Wei Xu,Yuanheng Wang
Abstract and Applied Analysis , 2012, DOI: 10.1155/2012/457024
Abstract: This paper deals with a new iterative algorithm for solving hierarchical fixed point problems of an infinite family of pseudocontractions in Hilbert spaces by , , and , where is a nonself -strictly pseudocontraction. Under certain approximate conditions, the sequence converges strongly to , which solves some variational inequality. The results here improve and extend some recent results.
Modified Relaxed Extragradient Method for a General System of Variational Inequalities and Nonexpansive Mappings in Banach Spaces
Yuanheng Wang,Liu Yang
Abstract and Applied Analysis , 2012, DOI: 10.1155/2012/818970
Abstract: The purpose of this paper is to introduce a new modified relaxed extragradient method andstudy for finding some common solutions for a general system of variational inequalitieswith inversestrongly monotone mappings and nonexpansive mappings in the framework ofreal Banach spaces. By using the demiclosedness principle, it is proved that the iterativesequence defined by the relaxed extragradient method converges strongly to a commonsolution for the system of variational inequalities and nonexpansive mappings under quitemild conditions.

Do Clonal Plants Show Greater Division of Labour Morphologically and Physiologically at Higher Patch Contrasts?
Zhengwen Wang,Yuanheng Li,Heinjo J. During,Linghao Li
PLOS ONE , 2012, DOI: 10.1371/journal.pone.0025401
Abstract: When growing in reciprocal patches in terms of availability of different resources, connected ramets of clonal plants will specialize to acquire and exchange locally abundant resources more efficiently. This has been termed division of labour. We asked whether division of labour can occur physiologically as well as morphologically and will increase with patch contrasts.

Abstract: With the Shift-share Method, the international visitor arrivals statistical data and sampling survey data from 1999 to 2005 of Shanghai and the provinces of the Yangtze River Valley(YRV) have been analyzed, indicating that the contribution of structural shifted components plays a leading role, and the contribution of share components plays a fundamental role in the in-flow and out-flow tourist increment in the provinces of the YRV from or to Shanghai. The competitive shifted components also make contributions but their effect is obviously less than other components. Generally, the structural shifted components and the share components highly concentrate in Shanghai's two neighboring provinces of Zhejiang and Jiangsu, showing a highly regional agglomeration;however, as for the component contributions to the in-flow and out-flow tourist increments in Shanghai, there exists disproportionality in influence in the various provinces of the Yangtze River Delta. To be more specific, the intensity of tourist flow from Shanghai, from east to west, shows a U-shaped distribution. In addition, although the spatial distance is an important factor affecting the change of spatial difference of tourist flow, the regional differences of tourism resource endowment, traffic, characteristics and supply of tourist products and the regional tourism integration, are the fundamental causes affecting tourism interaction between the metropolis and its region, and the change of tourism spatial distribution. It is strategically important to develop regional tourism by promoting the tourism interaction between the metropolis and its region in different spatial scales, so as to realize harmonious development and improve tourism spatial efficiency in China.
Anti-periodic solutions for recurrent neural networks without assuming global Lipschitz conditions
Hong Zhang,Yuanheng Wu
Electronic Journal of Differential Equations , 2010,
Abstract: In this paper we study recurrent neural networks with time-varying delays and continuously distributed delays. Without assuming global Lipschitz conditions on the activation functions, we establish the existence and local exponential stability of anti-periodic solutions.
