Globally asymptotically
WebApr 12, 2024 · Moreover, the dynamical behavior of this model infers that if R 0 ⩽ 1, then the disease-free periodic solution is globally asymptotically stable, and if R 0 > 1, then the model possesses a positive periodic solution, which is globally asymptotically stable. These theoretical findings are further illustrated by the final numerical simulations. Webis globally asymptotically stable. But even if you’re given a specific state feedback gain matrix K, this is very hard to determine. So we’ll require the existence of a quadratic Lyapunov function that establishes exponential stability of the closed-loop system, i.e., a matrix P = PT > 0 for which V˙ (z,t) = zT (A(t)+BK)TP +P(A(t)+BK) z ...

WebMay 16, 2015 · If the zero solution of is uniformly asymptotically stable, then it is globally uniformly asymptotically stable. We can state a natural generalization of Theorem F with \(n = 2\) as follows. Theorem 4.2. If the zero solution of is uniformly asymptotically stable, then it is globally uniformly asymptotically stable. Proof WebJun 17, 2024 · In this paper, we have proposed a novel approach based on the well-known result on the global asymptotic stability of continuous-time nonlinear cascade systems and Lyapunov stability theorem to re-establish the stability of the predator–prey model ().The result has proved that the unique positive equilibrium point is globally asymptotically …
WebMoreover, for $\Re _{0}>1$ ℜ 0 > 1 , a unique positive endemic equilibrium exists which is globally asymptotically stable. The global stability of the equilibria is shown via Lyapunov function. It is also obtained that incomplete treatment of TB causes increase in disease infection while efficient treatment results in a reduction in TB. WebFeb 25, 2013 · The basic reproductive number R 0 of a discrete SIR epidemic model is defined and the dynamical behavior of the model is studied. It is proved that the disease free equilibrium is globally asymptotically stable if R 0 < 1, and the persistence of the model is obtained when R 0 > 1.The main attention is paid to the global stability of the endemic …
WebFeb 15, 2024 · In this paper, a layered, undirected-network-structure, optimization approach is proposed to reduce the redundancy in multi-agent information synchronization and improve the computing rate. Based on the traversing binary tree and aperiodic sampling of the complex delayed networks theory, we proposed a network-partitioning method for … WebAsymptomatically definition: Without exhibiting any symptom of disease. .
WebNov 22, 2024 · We provide a theoretical study of the model. We derive the basic reproduction number R0 $\mathcal R_0$ that determines the extinction and the persistence of the infection. We show that the disease-free equilibrium is globally asymptotically stable whenever R0≤1 $\mathcal R_0 \leq 1$, while when R0>1… Expand
