涉及无零点的亚纯函数的正规定则

作者：谢佳; 邓炳茂 刊期：2019年第03期

Let k be a positive integer,let h(z)■0 be a holomorphic functions in a domain D,and let F be a family of zero-free meromorphic functions in D,all of whose poles have order at least l.If,for each f∈P(f)(z)-h(z) has at most k+l-1 distinct zeros(ignoring multiplicity) in D,where P(f)(z)=f(k)(z)+a1(z)f((k-1)(z)+…+ak(z...

亚纯函数与其q-平移算子分担公共值的唯一性

作者：张水英; 刘慧芳 刊期：2019年第03期

In this paper, the uniqueness problems on meromorphic function f(z) of zero order sharing values with their q-shift f(qz + c) are studied. It is shown that if f(z) and f(qz + c) share one values CM and IM respectively, or share four values partially, then they are identical under an appropriate deficiency assumption.

作者：何玉萍; 陈祥恩 刊期：2019年第03期

Let G be a simple graph and f be a proper total coloring(or a total coloring in brief) of G. For any vertex u in G, Cf(u) denote the set of colors of vertex u and edges which incident with vertex u. Cf(u) is said to be the color set of vertex u under f. If Cf(u) = Cf(v)for any two distinct vertices u and v of G, then...

时间分数阶对流-扩散方程的有限差分解法

作者：马燕; Musbah; FS 刊期：2019年第03期

In this paper, three implicit finite difference methods are developed to solve one dimensional time fractional advection-diffusion equation. The fractional derivative is treated by applying right shifted Gr¨unwald-Letnikov formula of order α ∈(0, 1). We investigate the stability analysis by using von Neumann method ...

拟线性抛物型趋化模型的整体有界解研究

作者：刘丙辰; 董梦真 刊期：2019年第03期

In this paper,we consider a quasilinear parabolic-parabolic chemotaxis model with nonlinear diffusivity,aggregation and logistic damping source:■where k1 epu≤D(u) or k1 up≤D(u);k2 equ≤S(u)≤k3 equ;g(u)≤a-beku.It is proved that,if q b0 for some constant b0> 0,then there exists a unique classical solution which is...

三阶三点三个正解

作者：WU; Hong-ping 刊期：2019年第03期

In this paper,we study the existence of triple positive solutions for the nonlinear third-order three-point boundary value problem ■where η∈[0,1/2) is a constant,by using a fixed-point theorem due to Avery and Peterson,we establish results of triple positive solutions to the boundary value problem,and an example is...

二阶多智能体系统的领导-随从固定时间一致性

作者：陈茂黎; 王晓 刊期：2019年第03期

We analyse the fixed-time consensus problem for multi-agent systems with leaderfollower mode. Based on a follower’s observation structure for the leader’s information, it is proved that the estimation errors can be converged to zero at a fixed time. From this stability and a sliding mode structure, we derive a cont...

关于费马型微分-差分方程的整函数解

作者：刘丹; 邓炳茂; 杨德贵 刊期：2019年第03期

In this paper,we mainly discuss entire solutions of finite order of the following Fermat type differential-difference equation[f(k)(z)]2+[△cf(z)]2=1,and the systems of differential-difference equations of the from ■Our results can be proved to be the sufficient and necessary solutions to both equation and systems o...

Haar散射变换下的多模态学习

作者：王娟; 赵杰 刊期：2019年第03期

In this paper, we propose a novel application of Haar scattering transform to learn features over multiple modalities data. A series of tasks for multimodal learning are presented, and the way of multimodal feature learning is shown. Furthermore, we validate our methods on several datasets with an classification task...
