Extremal Problems on Components and Loops in Graphs

作者：Sadik; DELEN; Ismail; Naci; CANGUL 刊期：2019年第02期

The authors recently defined a new graph invariant denoted by Ω(G) only in terms of a given degree sequence which is also related to the Euler characteristic. It has many important combinatorial applications in graph theory and gives direct information compared to the better known Euler characteristic on the realizab...
Three Series Theorem for Independent Random Variables under Sub-linear Expectations with Applications

作者：Jia; Pan; XU; Li; Xin; ZHANG 刊期：2019年第02期

In this paper, motived by the notion of independent and identically distributed random variables under the sub-linear expectation initiated by Peng, we establish a three series theorem of independent random variables under the sub-linear expectations. As an application, we obtain the Marcinkiewicz’s strong law of la...
Inequalities for the Extended Best Polynomial Approximation Operator in Orlicz Spaces

作者：Sonia; ACINAS; Sergio; FAVIER; Felipe; ZO 刊期：2019年第02期

In this paper we pursue the study of the best approximation operator extended from L^Φ to L~φ, where φ denotes the derivative of the function Φ. We get pointwise convergence for the coefficients of the extended best approximation polynomials for a wide class of function f, closely related to the Calder′on–Zygmund c...
Automorphisms of Extensions of Q by a Direct Sum of Finitely Many Copies of Q

作者：He; Guo; LIU; Yu; Lei; WANG; Ji; Ping; ZHANG 刊期：2019年第02期

Let G be an extension of Q by a direct sum of r copies of Q.(1) If G is abelian, then G is a direct sum of r + 1 copies of Q and Aut G = GL(r + 1, Q);(2) If G is non-abelian, then G is a direct product of an extraspecial Q-group E and m copies of Q, where E/ζ E is a linear space over Q with dimension 2 n and m + 2 n ...
Quadratic Lie Superalgebras Generalized by Balinsky–Novikov Superalgebras

作者：Yi; TAO; Zhi; Qi; CHEN; Yan; WANG 刊期：2019年第02期

Balinsky–Novikov superalgebras were introduced by Balinsky for constructing super-Virasoro type Lie superalgebras. In this paper, we give sufficient and necessary conditions for a Lie superalgebra generalized by a Balinsky–Novikov superalgebra with dimension 2|2 to be a quadratic Lie superalgebra.
Radial Operators on the Weighted Bergman Spaces over the Polydisk

作者：Ran; LI; Yu; Feng; LU 刊期：2019年第02期

In this paper, we study radial operators in Toeplitz algebra on the weighted Bergman spaces over the polydisk by the(m, λ)-Berezin transform and find that a radial operator can be approximated in norm by Toeplitz operators without any conditions. We prove that the compactness of a radial operator is equivalent to the...
Coincidence Wecken Property for Nilmanifolds

作者：Daciberg; GONCALVES; Peter; WONG 刊期：2019年第02期

Let f, g: X → Y be maps from a compact infra-nilmanifold X to a compact nilmanifold Y with dim X ≥ dim Y. In this note, we show that a certain Wecken type property holds, i.e., if the Nielsen number N(f, g) vanishes then f and g are deformable to be coincidence free. We also show that if X is a connected finite com...
Reconstruction of Splines from Nonuniform Samples

作者：Qing; Yue; ZHANG; Wen; Chang; SUN 刊期：2019年第02期

In this paper, we study the reconstruction of spline functions from their nonuniform samples. We investigate the existence and uniqueness of the solution of the following problem: for given data {(x_n, y_n) : n ∈ Z}, find a cardinal spline f(x), of a given degree, satisfying yn = f(x_n), n ∈ Z.Several necessary and...
On Quasi-weakly Almost Periodic Points of Continuous Flows

作者：Qi; YAN; Jian; Dong; YIN 刊期：2019年第02期

Let X be a compact metric space, F : X ×R → X be a continuous flow and x ∈ X a proper quasi-weakly almost periodic point, that is, x is quasi-weakly almost periodic but not weakly almost periodic. The aim of this paper is to investigate whether there exists an invariant measure generated by the orbit of x such that...
Empirical Likelihood Inference for Functional Coefficient ARCH-M Model

作者：Hai; Qing; ZHAO; Yuan; LI; Yan; Meng; ZHAO 刊期：2019年第02期

Empirical likelihood inference for parametric and nonparametric parts in functional coefficient ARCH-M models is investigated in this paper. Firstly, the kernel smoothing technique is used to estimate coefficient function δ(x). In this way we obtain an estimated function with parameter β.Secondly, the empirical likel...
