The purpose of this paper is to construct near-vector spaces using a result by Van der Walt, with Z<sub>p</sub> for p a prime, as the underlying near-field. There are two notions of near-vector spaces, we focus on those studied by André [1]. These near-vector spaces have recently proven to be very useful in finite linear games. We will discuss the construction and properties, give examples of these near-vector spaces and give its application in finite linear games. 展开更多

The purpose of this article is to define and characterize the general function space F(p, q, s) on Ω. Characterizing functions in the F(p, q, s) space is a work of considerable interest nowadays. In this article, the authors give several equivalent descriptions of the functions in the F(p, q, s) space on Ω in terms of fractional differential operators. At the same time, the authors give the relationship between F(p, q, s) space and Bloch type space on Ω too. 展开更多

Extending the results of an article published in(Acta Mathematica Sinica(2016,59(4)) by the author, for a sequence of normed spaces {Xi}, the representation problem of conjugate spaces of some l^0({X_i}) type F-normed spaces are studied in this paper. The algebraic representation continued equalities l^0({X_i}) * A=c_(00)~0({X_i}) * A= c_(00)({X_i~*}),(l^0(X))~* A=(c^0(X) )~* A=(c_0~0(X))~* A=(c_(00)~0(X))~* A= c_(00)(X~*)are obtained in the first part. Under weak-star topology, the topological representation c_(00)~0({X_i}) ~*, w~* = c_(00)~0({X_i~*}) is obtained in the second part. For the sequence of inner product spaces and number fields with the usual topology, the concrete forms of the basic representation theorems are obtained at last. 展开更多

A class of generalized vector variational-type inequality problems (GVVTIP) are studied in FC-spaces, which includes the most of vector equilibrium problems, vector variational inequality problems, generalized vector equilibrium problems and general- ized vector variational inequality problem as special cases. By using F-KKM theorem, some new existence results for GVVTIP axe established in noncompact FC-space. As consequences, some recent known results in literature are obtained under much weaker assumption. 展开更多

The space of internal geometry of a model of a real crystal is supposed to be finite, closed, and with a constant Gaussian curvature equal to unity, permitting the realization of lattice systems in accordance with Fedorov groups of transformations. For visualizing computations, the interpretation of geometrical objects on a Clifford surface (SK) in Riemannian geometry with the help of a 2D torus in a Euclidean space is used. The F-algorithm ensures a computation of 2D sections of models of point systems arranged perpendicularly to the symmetry axes l3, l4, and l6. The results of modeling can be used for calculations of geometrical sizes of crystal structures, nanostructures, parameters of the cluster organization of oxides, as well as for the development of practical applications connected with improving the structural characteristics of crystalline materials. 展开更多

Banach压缩映射原理在非线性分析中起着重要作用,它是解决完备度量空间中不动点的存在性和唯一性问题的有效方法,在基础数学和应用数学中有着广泛的应用,近年来该定理在多个方面得到了推广。在b-度量空间的背景下,研究一类新的F-型压缩映射对的公共不动点定理。首先,在b-度量空间中引入一类新的平方型F-型压缩条件;其次,利用2个映射的包含关系,构造一个序列,并通过使用F-函数的性质、数学归纳法及压缩条件证明该序列相邻项距离的极限为零,进而得到该序列是一个柯西列;最后,结合空间的完备性和压缩条件,得出2个映射具有重合值,再利用映射的弱相容条件,进一步证明该映射对具有公共不动点,同时给出了一个具体例子来说明结果的有效性。 展开更多
