SOME EULER SPACES OF DIFFERENCE SEQUENCES OF ORDER m

Kizmaz [13] studied the difference sequence spaces ∞（A）, c（A）, and co（A）. Several article dealt with the sets of sequences of m-th order difference of which are bounded, convergent, or convergent to zero. Altay and Basar [5] and Altay, Basar, and Mursaleen [7] introduced the Euler sequence spaces e0^r, ec^r, and e∞^r, respectively. The main purpose of this article is to introduce the spaces e0^r△^（m））, ec^r△^（m））, and e∞^r△^（m））consisting of all sequences whose mth order differences are in the Euler spaces e0^r, ec^r, and e∞^r, respectively. Moreover, the authors give some topological properties and inclusion relations, and determine the α-, β-, and γ-duals of the spaces e0^r△^（m））, ec^r△^（m））, and e∞^r△^（m））, and the Schauder basis of the spaces e0^r△^（m））, ec^r△^（m））. The last section of the article is devoted to the characterization of some matrix mappings on the sequence space ec^r△^（m））.

CHARACTERIZATIONS OF COMPACT OPERATORS ON SOME EULER SPACES OF DIFFERENCE SEQUENCES OF ORDER m

In the past, several authors studied spaces of m-th order difference sequences, among them, H.Polat and F.Basar （[17]） defined the Euler spaces of m-th order difference sequences e r 0 （△ （ m ） ）, e r c （△ （ m ） ） and e r ∞ （△ （ m ） ） and characterized some classes of matrix transformations on them. In our paper, we add a new supplementary aspect to their research by characterizing classes of compact operators on those spaces. For that purpose, the spaces are treated as the matrix domains of a triangle in the classical sequence spaces c 0 , c and ∞ . The main tool for our characterizations is the Hausdorff measure of noncompactness.

添加剂对5μm电解铜箔性能及形貌的影响

电解铜箔因其具有强度高、延展性良好等优势被广泛应用于新能源领域,目前对于5μm电解铜箔性能的影响因素研究较少。本文采用单一变量法考察了PEG、HVP和HP等添加剂对Cu电沉积的影响,通过正交试验探究PEG、HVP和HP复合添加剂对5μm电解铜箔性能的影响,并对比了不同添加剂对5μm电解铜箔外观形貌的影响,得到如下结论:PEG和HVP具有增强极化的作用,且随着浓度的增加极化作用增强,HP具有去极化的作用,且随着浓度的增加去极化作用增强;通过正交试验得出的最优复合添加剂的浓度为PEG 0.36 g/L、HVP 0.12 g/L、HP 0.05 g/L,在此条件下得到的较佳性能为抗拉强度485.17 MPa、延伸率3.72%、粗糙度1.31;相比于单一添加剂,最优配比复合添加剂下的复合镀层表面更加均匀平整,且颗粒细小。

Some Characterizations of Hereditarily Indecomposable Banach Spaces

In this paper we first discuss the relations between some G-M-type spaces, and the previous eight kinds of G-M-type Banach spaces are merged into four different kinds. Then we build a Generalized Operator Extension Theorem, and introduce the concept of complete minimal sequences. Some sufficient and necessary conditions under which a Banach space is a hereditarily indecomposable space are given. Finally, we give some characterizations of hereditarily indecomposable Banach Spaces.

LAVRENTIEV'S REGULARIZATION METHOD FOR NONLINEAR ILL-POSED EQUATIONS IN BANACH SPACES

In this paper, we deal with nonlinear ill-posed problems involving m-accretive mappings in Banach spaces. We consider a derivative and inverse free method for the imple- mentation of Lavrentiev regularization method. Using general HSlder type source condition we obtain an optimal order error estimate. Also we consider the adaptive parameter choice strategy proposed by Pereverzev and Schock （2005） for choosing the regularization parameter.

On M-Asymmetric Irresolute Multifunctions in Bitopological Spaces

In this paper, our focus is to introduce and investigate a class of mappings called M-asymmetric irresolute multifunctions defined between bitopological structural sets satisfying certain minimal properties. M-asymmetric irresolute multifunctions are point-to-set mappings defined using M-asymmetric semiopen and semiclosed sets. Some relations between M-asymmetric semicontinuous multifunctions and M-asymmetric irresolute multifunctions are established. This notion of M-asymmetric irresolute multifunctions is analog to that of irresolute multifunctions in the general topological space and, upper and lower M-asymmetric irresolute multifunctions in minimal bitopological spaces, but mathematically behaves differently.

建筑师俞挺新近完成的"M-Space"小美术馆是对碎片化的外在环境和历史文脉的一次敏感的回应。对偶的设计思维促使他在美术馆、图书馆和博物馆三者之间采取不同的设计策略,并表现为纯粹、轻透的新建体量与复杂、矛盾的室内改造之间的对比。半透明表皮体现了江南意味的光影关系。建筑师对非形似熟悉感的追求使其将营造氛围放到了设计的首位。

HP-STMCs空间堆热管运行参数计算

利用自主开发的热管蒸汽流动计算程序SNPS-HPD对HP-STMCs堆堆芯锂热管和辐射散热器钾热管稳态运行时的性能参数进行了分析计算,得到了不同运行条件下锂热管和3类散热器钾热管内部蒸汽流动的压强、温度、速度和流动马赫数分布情况。结果表明:堆芯锂热管内部蒸汽压力和温度在蒸发段均有较大下降,在绝热段呈线性下降,而在冷凝段有一定的回升。锂热管温降主要为内部蒸汽的温降,且蒸汽温降随输出功率的增加而减小;蒸汽轴向马赫数在绝热段出口处达到最大,且随输出功率的增大而减小;辐射散热器钾热管具有良好的等温性,但热管绝热段的设计增加了热管蒸汽的温降,破坏了热管的等温性。

CONVERGENCE OF DOUBLE WALSH-FOURIER SERIES AND HARDY SPACES

It is proved that the maximal operator of the Marczinkiewicz-Fejér meams of a double Walsh-Fourier series is bounded from the two-dimensional dyadic martingale Hardy space H p to L p (2/3<p<∞) and is of weak type (1,1). As a consequence we obtain that the Marczinkiewicz-Fejér means of a function f∈L 1 converge a.e. to the function in question. Moreover, we prove that these means are uniformly bounded on H p whenever 2/3<p<∞. Thus, in case f∈H p , the Marczinkiewicz-Fejér means conv f in H p norm. The same results are proved for the conjugate means, too.
