On Fuzzy Preordered Structures and （Fuzzy） Hyperstructures

This article presents a connection between fuzzy preordered structures and hyperstructures. Firstly, we introduce the notion of fuzzy preordered semigroup and then, we construct a semihypergroup associated with it, giving some properties of the associated hyperstructure. Secondly, we define the notion of fuzzy preordered ring in order to construct a fuzzy hyperring.     

On Weighted α-Besov Spaces and α-Bloch Spaces of Quaternion-Valued Functions

In this paper, we give the definitions of weighted α-Besov-type spaces and α-Bloch spaces of quaternion-valued functions, then we obtain characterizations of these quaternion α-Bloch spaces by quaternion α-Besov-type spaces. Relations between Q _p norms and weighted α-Besov norms are also considered. The role of ρ?^α sequences in securing non-Bloch functions is highlighted in quaternion sense.     

On Galvin’s Lemma and Ramsey Spaces

An abstract version of Galvin??s lemma is proven, within the framework of the theory of Ramsey spaces. Some instances of it are explored.

On the Functional Estimation and Its Applications

In this paper, the following results are obtained. The functional estimation theorem: Let X, Y be linear spaces, normedbu ‖·‖_X, ‖·‖_Y, respectively: X be a subspace of X: Y(?)Y. Suppose that F is a functional on X×Y to [0, ∞). which has the properties : F(f_1 f_2, g) F(f_1, g) F(f_2, g), and F(f, g)相似文献   

On Smarandache Multiplicative Sequence and Its Generation

The main purpose of this paper is to introduce the general Smarandache multiplicative sequence based on the Smarandache multiplicative sequence, and calculate the value of some infinite series involving these sequences.     

On Some Twistor Spaces Over 4ℂℙ2

We show that for any positive integer there exist on 4², the connected sum of four complex projective planes, twistor spaces whose algebraic dimensions are two. Here, appears as the order of the normal bundle of C in S, where S is a real smooth half-anti-canonical divisor on the twistor space and C is a real smooth anti-canonical divisor on S. This completely answers the problem posed by Campana and Kreussler. Our proof is based on the method developed by Honda, which can be regarded as a generalization of the theory of Donaldson and Friedman.     

On Absolute Nörlund Spaces and Matrix Operators

In a more recent paper, the second author has introduced a space |C_α|_k as the set of all series by absolute summable using Ces`aro matrix of order α -1. In the present paper we extend it to the absolute N?rlund space |N_p~θ|_k taking N?rlund matrix in place of Ces`aro matrix, and also examine some topological structures, α-β-γ-duals and the Schauder base of this space. Further we characterize certain matrix operators on that space and determine their operator norms, and so extend some well-known results.     

On Hereditarily Indecomposable Banach Spaces

This paper shows that every non-separable hereditarily indecomposable Banach space admits an equivalent strictly convex norm, but its bi-dual can never have such a one; consequently, every non-separable hereditarily indecomposable Banach space has no equivalent locally uniformly convex norm.     

On Levine–O'Sullivan's Sequence and Its Conjecture

Let q_1=1,and q_n be the largest value of(k+1)(n-q_k) for all integers 1≤k≤n-1with n≥2.The sequence Q={q1,q2,q3,...} is called Levine–O'Sullivan sequence.In this paper,we use the combinational and analysis skill and the mathematical induction to study the asymptotic properties of q_n,and give an interesting asymptotic formula for it.This solved a conjecture proposed by Professor Chen Yonggao.

On the WAε Property and g-NUCε Banach Spaces

The WAε property and g-NUCε, g-NUC Banach spaces are introduced. We prove that the WAε property is equivalent to the WBS property and the g-NUCε (resp., g-NUC) spaces are equivalent to the NUCε (resp. , NUC) spaces possessing the BS property. So we obtain a characterization of the NUCε (resp, , NUC) spaces possessing the BS property.     

On the General Interpolation Formulas for Discrete Functional Spaces (Ⅰ)

The general interpolation formulas for discrete functional spaces of discrete functions with one index are presented in the note. These are the relationship among the discrete norms in the forms of the summation of powers, the maximum modulo, the Hölder and Lipschitz coefficients for the discrete functions.
