Semi-Hyers–Ulam–Rassias Stability of the Convection Partial Differential Equation via Laplace Transform

Mathematics, 2021
In this paper, we study the semi-Hyers–Ulam–Rassias stability and the generalized semi-Hyers–Ulam–Rassias stability of some partial differential equations using Laplace transform. One of them is the convection partial differential equation.

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.

On Hyers-Ulam stability of generalized linear functional equation and its induced Hyers-Ulam programming problem

, 2016
We propose a new approach called Hyers-Ulam programming to discriminate whether a generalized linear functional equation, with the form for functions from a normed space into a Banach space, has the Hyers-Ulam stability or not. Our main result is that if

On the Well‐Posedness and Stability Analysis of Nonlinear Fractional Integrodifferential Equations Subject to Integral Boundary Constraints

Abstract and Applied Analysis, Volume 2026, Issue 1, 2026.
This article investigates the existence, uniqueness, and stability of solutions for a class of nonlinear fractional integrodifferential equations (NLFIDEs) with nonlocal boundary conditions in Banach algebras. By employing advanced analytical techniques within the Banach algebra framework, we rigorously establish existence and uniqueness results and ...
