研发合作联盟的稳定性研究
研发合作 联盟 短视稳定性 远视稳定性
2022/3/30
针对企业研发阶段合作、生产阶段竞争的情形，研究了研发合作联盟的稳定结构。首先利用两阶段博弈的方法给出了任意联盟结构中每个企业的均衡研发投入水平、产量以及利润，接着利用Nash稳定性方法和最大一致集（LCS）方法分别探讨了联盟的短视稳定性以及远视稳定性。结果表明，研发联盟的短视稳定性与远视稳定性结果一致，即溢出率小于0.5时只有两人联盟结构稳定；溢出率大于0.5时，只有大联盟结构稳定。
一类具有媒体报道的传染病模型
媒体报道 传染病模型 局部稳定性 全局稳定性
2022/3/23
将媒体报道量M视为时间t的函数，利用非连续函数β/(1+εMI)来刻画媒体报道对传染率的影响，建立了一个分段光滑的SIM传染病模型，给出了模型的非负平衡点的存在性。利用微分方程线性化稳定性理论分析，得到了系统的各平衡点局部稳定的阈值条件，并进一步利用Poincare-Bendixon定理给出了正平衡点全局渐近稳定的充分条件。

The Gardner equation and the L^2-stability of the N-soliton solution of the Korteweg-de Vries equation
KdV equation Gardner equation integrability multi-soliton stability
2011/2/25
Multi-soliton solutions of the Korteweg-de Vries equation (KdV)are shown to be globally L2-stable, and asymptotically stable in the sense of Martel-Merle [23]. The proof is surprisingly simple and com...
Momentum Regularity and Stability of the Relativistic Vlasov-Maxwell-Boltzmann System
Momentum Regularity Stability Relativistic Vlasov-Maxwell-Boltzmann System
2011/1/18
In the study of solutions to the relativistic Boltzmann equation,their regularity with respect to the momentum variables has been an outstanding question, even local in time, due to the initially unex...

Existence of approximate Hermitian-Einstein semi-stable bundles
2011/1/19
The purpose of this paper is to investigate canonical metrics on a semi-stable vector bundle E over a compact K¨ahler manifold X. It is shown that, if E is semistable,then Donaldson’s functional is bo...
We show that if p is an odd prime then p−1 X k=0 EkEp−1−k 1 (mod p) and p−3 X k=0 EkEp−3−k (−1)(p−1)/22Ep−3 (mod p),where E0,E1,E2, . . . are ...
Nonlinear Stabilization under Sampled and Delayed Measurements, and with Inputs Subject to Delay and Zero-Order Hold
feedback stabilization time-delay systems sampled-data systems nonlinear control
2011/1/20
Sampling arises simultaneously with input and output delays in networked control systems. When the delay is left uncompensated, the sampling period is generally required to be sufficiently small, the ...

The asymptotic expansion of Tracy-Widom GUE law and symplectic invariants
asymptotic expansion of Tracy-Widom GUE law symplectic invariants
2010/12/28
We establish the relation between two objects: an integrable system related to Painlev´e II equation, and the symplectic invariants of a certain plane curve TW. This curve describes the average...
Constructive Proof of Global Lyapunov Function as Potential Function
Constructive Proof Global Lyapunov Function Potential Function
2010/12/28
We provide a constructive proof on the equivalence of two fundamental concepts: the global
Lyapunov function in engineering and the potential function in physics, establishing a bridge be-tween these...
Localisation and Completion with an addendum on the use of Brown-Peterson homology in stable homotopy
Localisation Completion addendum
2011/2/25
In spring 1973 Frank Adams gave a course at the University of Chicago on localisation and completion. This was in the very early days of the subject,which arose from disparate constructions of Quillen...
Asymptotic stability of spin orbit resonance for the dynamics of a viscoelastic satellite
Asymptotic stability spin orbit resonance dynamics viscoelastic satellite
2011/2/25
We prove the asymptotic stability of 1:1 spin orbit resonance for a stiff viscoelastic rotationally invariant satellite. The main point is that we do not assume any dissipation on the orbital degrees ...
