研究无向拓扑下多智能体系统的固定时间和有限时间的比例一致性问题。利用集值映射、微分包含和Lyapunov稳定性理论,给出多智能体系统达到固定时间和有限时间比例一致的判别准则。最后,给出一个实例,验证结论的可行性和有效性。
针对私企同部门技术工人再培训问题,构建了动力学模型.分析了技术工人再培训的唯一正平衡点与非负平衡点的局部稳定性和正平衡点的全局稳定性,进一步利用Matlab对相关结果进行拟合验证.
Braid Floer homology is an invariant of proper relative braid classes. Closed integral curves of 1-periodic Hamiltonian vector fields on the 2-disc may be regarded as braids. If the Braid Floer homolo...
In the paper, by introducing two pairs of conjugate exponents(p,q) and (r,s), we establish a new generalizations of the Hilbert-type ineqaulity with a best constant. As application, the reverse and it...
Oriented closed curves on an orientable surface with boundary are described up to continuous deformation by reduced cyclic words in the generators of the fundamental group and their inverses.
The bondage number b(G) of a graph G is the smallest number of edges of G whose removal from G results in a graph having the domination number larger than that of G. We show that, for a graph G having...
Let A+ denote the set of Laplace transforms of complex Borel measures μ on [0,+1) such that μ does not have a singular non-atomic part. In [1], an extension of the classical -metric of Vinnicombe was...
Three philosophical principles are often quoted in connection with Leib-niz: “objects sharing the same properties are the same object”, “everything can possibly exist, unless it yields contradiction”,...
In [Vor05], Voronov gave life to the Cacti operad: An operad whose homology acts on the shifted homology of the free loop space over a compact, smooth orientable manifold M – HpMS1q– giving it the st...
In this work passive electric damping of structural vibrations by distributed piezoelectric transducers and electric networks is analyzed. Different distributed electric controllers are examined as fi...

基本圈与图的曲面嵌入     基本圈  最大亏格  上嵌入       2009/8/31
本文研究图的基本圈与图在可定向曲面上的嵌入之间的关系. 本文结果表明: 一个图~$G$ 可以嵌入到亏格至少为~$g$ 的可定向曲面上的充分必要条件是: 对于~$G$ 中任意一个支撑树~$T$, 存在一个基本圈序列~$C_1,C_2,\ldots,C_{2g}$, 使得对于每一个~$i:1\leq i\leq g,C_{2i-1}\cap{C_{2i}}\neq\emptyset$. 特别地, 在~...
指出了流形算法中利用测地线寻找最优解存在附加度量结构和计算复杂的问题,根据流形的局部与欧氏空间零点的开邻域光滑同胚这一性质,利用坐标变换把非线性等式约束优化问题转化为无约束优化问题,利用坐标变换而不是黎曼几何结构给出了函数取得极值的充分和必要条件,构造了一种映射梯度算法,并证明这种算法是线性收敛的.
