Hyers-Ulam stability for coupled random fixed point theorems and applications to periodic boundary value random problems [PDF]
, 2019 In this paper, we prove some existence, uniqueness and Hyers-Ulam stability results for the coupled random fixed point of a pair of contractive type random operators on separable complete metric spaces. The approach is based on a new version of the Perov

Approximate Homomorphisms of Ternary Semigroups
, 2005 A mapping $f:(G_1,[ ]_1)\to (G_2,[ ]_2)$ between ternary semigroups will be called a ternary homomorphism if $f([xyz]_1)=[f(x)f(y)f(z)]_2$. In this paper, we prove the generalized Hyers--Ulam--Rassias stability of mappings of commutative semigroups into ...

Asian Journal of Control, Volume 28, Issue 1, Page 34-45, January 2026.Abstract We study a nonlinear ψ−$$ \psi - $$ Hilfer fractional‐order delay integro‐differential equation ( ψ−$$ \psi - $$ Hilfer FrODIDE) that incorporates N−$$ N- $$ multiple variable time delays. Utilizing the ψ−$$ \psi - $$ Hilfer fractional derivative ( ψ−$$ \psi - $$ Hilfer‐FrD), we investigate the Ulam–Hyers––Rassias (U–H–R), semi‐Ulam–Hyers ...

Radar Recognition Method Based on Signal Pre‐Trained Model of Satellite Borne Passive Detection Data
IET Radar, Sonar &Navigation, Volume 20, Issue 1, January/December 2026.We propose a stable pretraining model based on generalised autoencoder, which can adapt to pulse sequence data with low dimensionality, high loss rate and false pulse interference conditions, improving the model's feature representation ability and downstream task performance.
