In this paper, the author first introduces the concept of
generalized algebraic cone metric spaces and some elementary results
concerning generalized algebraic cone metric spaces. Next, by using
these results, some new fixed point theorems on generalized
(complete) algebraic cone metric spaces are proved and an example is
given. As a consequence, the main results generalize the
corresponding results in complete algebraic cone metric spaces and
generalized complete metric spaces. 相似文献

By constructing a correspondence relationship between independence spaces and posets, under isomorphism, this paper characterizes loopless independence spaces and applies this characterization to reformulate certain results on independence spaces in poset frameworks. These state that the idea provided in this paper is a new approach for the study of independence spaces. We outline our future work finally. 相似文献

In this paper we consider generalized Hardy spaces which include classical Hardy spaces and Hardy-Lorentz spaces as special
cases. We give real interpolation results for such spaces. As applications, we solve an interpolation problem for Besov spaces
of generalized smoothness and prove the boundedness of pseudodifferential operators acting both in these spaces and in the
local Hardy spaces. For the latter spaces, we also obtain wavelet decompositions. 相似文献

In 1989, Das and Patel considered known sequence spaces to define two new sequence spaces called lacunary almost convergent and lacunary strongly almost convergent sequence spaces, and proved two inclusion theorems with respect to those spaces. In this paper, we shall extend those spaces to two new double sequence spaces and prove multidimensional analogues of Das and Patel’s results. 相似文献

We introduce a one-step implicit iterative method for two finite families of asymptotically nonexpansive mappings in a hyperbolic space and use it to approximate common fixed points of these families. The results presented in this paper are new in the setting of hyperbolic spaces. On top, these are generalizations of several results in literature from Banach spaces to hyperbolic spaces. At the end of the paper, we give an example to validate our results. 相似文献

In this paper we prove some general theorems on the existence of continuous order-preserving functions on topological spaces
with a continuous preorder. We use the concepts of network and netweight to prove new continuous representation theorems and
we establish our main results for topological spaces that are countable unions of subspaces. Some results in the literature
on path-connected, locally connected and separably connected spaces are shown to be consequences of the general theorems proved
in the paper. Finally, we prove a continuous representation theorem for hereditarily separable spaces. 相似文献

In this paper we prove some fixed points results on cone metric spaces for maps satisfying general contractive type conditions. Among other things, we extend some results of Nguyen [11] from metric spaces to cone metric spaces. The example is included. 相似文献

The aim of this paper is to propose an abstract construction of spaces which keep the main properties of the (already known) Hardy spaces H1. We construct spaces through an atomic (or molecular) decomposition. We prove some results about continuity from these spaces into L1 and some results about interpolation between these spaces and the Lebesgue spaces. We also obtain some results on weighted norm inequalities. Finally we present partial results in order to understand a characterization of the duals of Hardy spaces. 相似文献

In this paper, we prove some common fixed point theorems for any even number of compatible mappings in complete intuitionistic
fuzzy metric spaces. Our main results extend and generalize some known results in fuzzy metric spaces and intuitionistic fuzzy
metric spaces. 相似文献

In this paper we present a simple and unified approach to the fixed point results on cone symmetric spaces and metric type spaces based on symmetric spaces fixed point theory. We also give a new characterization of semi-metric spaces with open balls. 相似文献

This paper is about certain linear subspaces of Banach SN spaces (that is to say Banach spaces which have a symmetric nonexpansive linear map into their dual spaces). We apply our results to monotone linear subspaces of the product of a Banach space and its dual. In this paper, we establish several new results and also give improved proofs of some known ones in both the general and the special contexts. 相似文献

紧致齐性空间上的调和分析(Ⅰ):富里埃级数的Poisson求和 总被引:2,自引:0,他引:2
首先介绍了紧致齐性空间上调和分析的若干基础性结果,并给出这些结果的较简洁的证明。接着,我们定义了紧致齐性空间上函数的卷积(熟知n维球面是一个紧致齐性空间),这一定义看来对研究紧致齐性空间上的调和分析向题是相当有用的。最后,用定义的卷积,研究了紧致齐性空间上Fourier级数的Poisson求和。 相似文献
