Most recently, some new double sequence spaces , where and for have been introduced as the domain of four-dimensional generalized difference matrix in the double sequence spaces , where and for , and some topological properties, dual spaces, some new four-dimensional matrix classes and matrix transformations related to these spaces have also been studied by Tuğ and Başar and Tuğ (see [1], [2], [3], [4]). In this paper, we introduce new strongly almost convergent double sequence spaces and whose -transforms are in the spaces and , respectively. The main body of this paper is designed by the investigation of the following hypothesis. Firstly, we examine some topological properties and inclusion relations including the new double sequence spaces and . Also, we determine the α-dual, -dual and γ-dual of the space . Finally, we give the necessary and sufficient conditions on an infinite matrix transforming from over , and we also characterize the classes , and .

最近,一些新的双序列空间 , 在哪里 和 为了 已作为四维广义差分矩阵的域引入 在双序列空间 , 在哪里 和 为了 ,Tuğ和Başar和Tuğ还研究了一些拓扑特性,对偶空间,一些新的三维矩阵类以及与这些空间有关的矩阵变换(请参见[1],[2],[3],[4] )。在本文中,我们介绍了新的强几乎收敛的双序列空间 和 谁的 -转换在空格中 和 , 分别。本文的主体是通过以下假设的研究而设计的。首先,我们研究了一些拓扑特性和包含关系,包括新的双序列空间 和 。此外,我们确定α-对偶,对偶和γ对偶。最后,我们给出了从 超过 ,并且我们还对类进行了表征 , 和 。
