Stability Analysis of Nonlinear Time-Varying Systems by Lyapunov Functions with Indefinite Derivatives [PDF]
IET Control Theory & Applications, 11(9): 1434-1442 (2017), 2015 This paper is concerned with stability analysis of nonlinear time-varying systems by using Lyapunov function based approach. The classical Lyapunov stability theorems are generalized in the sense that the time-derivative of the Lyapunov functions are allowed to be indefinite.

Hyers–Ulam stability for a partial difference equation [PDF]
Electronic Journal of Qualitative Theory of Differential Equations, 2021 Under the exponential trichotomy condition we study the Hyers–Ulam stability for the linear partial difference equation: \[ x_{n+1,m}=A_nx_{n,m}+B_{n,m}x_{n,m+1}+f(x_{n,m}),\qquad n,m\in \mathbb{Z} \] where $A_n$ is a $k\times k$ matrix whose elements are sequences of $n$, $B_{n,m}$ is a $k\times k$ matrix whose elements are double sequences of $m,n ...

Efficiency and Stability in a Process of Teams Formation [PDF]
, 2021 Motivated by data on coauthorships in scientific publications, we analyze a team formation process that generalizes matching models and network formation models, allowing for overlapping teams of heterogeneous size. We apply different notions of stability: myopic team-wise stability, which extends to our setup the concept of pair-wise stability ...

Asymptotic stability of the Cauchy and Jensen functional equations [PDF]
, 2016 The aim of this note is to investigate the asymptotic stability behaviour of the Cauchy and Jensen functional equations. Our main results show that if these equations hold for large arguments with small error, then they are also valid everywhere with a ...

On Generalized Hyers‐Ulam Stability of Admissible Functions [PDF]
Abstract and Applied Analysis, 2012 We consider the Hyers‐Ulam stability for the following fractional differential equations in sense of Srivastava‐Owa fractional operators (derivative and integral) defined in the unit disk: , in a complex Banach space. Furthermore, a generalization of the admissible functions in complex Banach spaces is imposed, and applications are illustrated.
