Polynomial asymptotic stability of damped stochastic differential equations [PDF]
Electronic Journal of Qualitative Theory of Differential Equations, 2004 The paper studies the polynomial convergence of solutions of a scalar nonlinear It\^{o} stochastic differential equation\[dX(t) = -f(X(t))\,dt + \sigma(t)\,dB(t)\] where it is known, {\it a priori}, that $\lim_{t\rightarrow\infty} X(t)=0$, a.s.

On a logarithmic criterion for uniform polynomial stability
Annals of the West University of Timisoara: Mathematics and Computer Science, 2018 The paper presents a logarithmic criterion for uniform polynomial stability of evolution operators in Banach spaces. As applications, another four characterizations of uniform polynomial stability are obtained.

Stability of Real Parametric Polynomial Discrete Dynamical Systems [PDF]
Discrete Dynamics in Nature and Society, 2015 We extend and improve the existing characterization of the dynamics of general quadratic real polynomial maps with coefficients that depend on a single parameter λ and generalize this characterization to cubic real polynomial maps, in a consistent theory

On the Stability of Independence Polynomials
The Electronic Journal of Combinatorics, 2018 The independence polynomial of a graph is the generating polynomial for the number of independent sets of each size and its roots are called independence roots. We investigate the stability of such polynomials, that is, conditions under which the independence roots lie in the left half-plane.

Selecciones Matemáticas, 2018 We studied the uniform stabilization of a class of Timoshenko systems with partial dissipation of the beam. Our main result is to prove that the semigroup associated to this model has polynomial decay.

Les polynômes eul\IeC èriens stables de type B [PDF]
Discrete Mathematics & Theoretical Computer Science, 2012 We give a multivariate analog of the type B Eulerian polynomial introduced by Brenti. We prove that this multivariate polynomial is stable generalizing Brenti's result that every root of the type B Eulerian polynomial is real.

The Stability Interval of the Set of Linear System [PDF]
International Journal of Electronics and Telecommunications, 2021 The article considers the problem of stability of interval-defined linear systems based on the Hurwitz and Lienard- Shipar interval criteria. Krylov, Leverier, and Leverier- Danilevsky algorithms are implemented for automated construction and analysis of

On the solution existence and stability of polynomial optimization problems
, 2021 International audienceIn this paper, we introduce and investigate a new regularity condition in the asymptotic sense for optimization problems whose objective functions are polynomial. The normalization argument in asymptotic analysis enables us to study

Axioms, 2022 This paper discusses the robust stability and stabilization of polynomial fractional differential (PFD) systems with a Caputo derivative using the sum of squares. In addition, it presents a novel method of stability and stabilization for PFD systems.

Gridding discretization-based multiple stability switching delay search algorithm: The movement of a human being on a controlled swaying bow. [PDF]
PLoS ONE, 2017 Delay represents a significant phenomenon in the dynamics of many human-related systems-including biological ones. It has i.a. a decisive impact on system stability, and the study of this influence is often mathematically demanding. This paper presents a
