Exact eigenvalue assignment of linear scalar systems with single delay using Lambert W function
, 2018 Eigenvalue assignment problem of a linear scalar system with a single discrete delay is analytically and exactly solved. The existence condition of the desired eigenvalue is established when the current and delay states are present in the feedback loop ...

Journal of Mathematics, Volume 2025, Issue 1, 2025.This paper analyzes the stability of the Euler–Lagrange–Jensen cubic functional equation in the context of Banach spaces and Intuitionistic Fuzzy Normed Spaces (IFN‐Spaces). We use both direct and fixed point techniques to establish the generalized Ulam stability of the cubic functional equation under various norm‐based constraints.

On a type of exponential functional equation and its superstability in the sense of Ger [PDF]
, 2013 In this paper, we deal with a type exponential functional equation as follows $$f(xy)=f(x)^{g(y)},$$ where $f$ and $g$ are two real valued functions on a commutative semigroup.

HYERS-ULAM STABILITY OF A PERTURBED GENERALISED LIENARD EQUATION
International Journal of Apllied Mathematics, 2019 In this paper, we consider the Hyers-Ulam stability of a perturbed generalized Lienard equation, using a nonlinear extension of Gronwall-Bellman integral inequality called the Bihari integral inequality.

Pseudo almost periodic solutions of an iterative equation with variable coefficients
, 2017 In this paper, the exponential dichotomy, and Tikhonov and Banach fixed point theorems are used to study the existence and uniqueness of pseudo almost periodic solutions of nonhomogeneous iterative functional differential equations of the form x.t/ D 1.t/

Fuzzy stability of multi-additive mappings
Demonstratio MathematicaThe main aim of this study is to establish some stability results concerning the multi-additive mappings by applying the so-called direct (Hyers) method and the alternative fixed approach in the setting of fuzzy normed spaces.

Stationary Distributions for Retarded Stochastic Differential Equations without Dissipativity [PDF]
, 2013 Retarded stochastic differential equations (SDEs) constitute a large collection of systems arising in various real-life applications. Most of the existing results make crucial use of dissipative conditions. Dealing with "pure delay" systems in which both

Fuzzy stabilities of a new hexic functional equation in various spaces
Analele Stiintifice ale Universitatii Ovidius Constanta: Seria Matematica, 2022 The advantage of various fuzzy normed spaces is to analyse impreciseness and ambiguity that arise in modelling problems. In this paper, various classical stabilities of a new hexic functional equation in di erent fuzzy spaces like fuzzy Banach space ...

Exponential Mixing for Retarded Stochastic Differential Equations [PDF]
, 2013 In this paper, we discuss exponential mixing property for Markovian semigroups generated by segment processes associated with several class of retarded Stochastic Differential Equations (SDEs) which cover SDEs with constant/variable/distributed time-lags.
