Advanced differential equations with piecewise constant argument deviations

International Journal of Mathematics and Mathematical Sciences, Volume 6, Issue 4, Page 671-703, 1983., 1983
Functional differential equations of advanced type with piecewise constant argument deviations are studied. They are closely related to impulse, loaded and, especially, to difference equations, and have the structure of continuous dynamical systems within intervals of unit length.

Mittag-Leffler-Hyers-Ulam stability for a first- and second-order nonlinear differential equations using Fourier transform

Demonstratio Mathematica
In this article, we apply the Fourier transform to prove the Hyers-Ulam and Hyers-Ulam-Rassias stability for the first- and second-order nonlinear differential equations with initial conditions.

Analysis Of A Vector-Borne Diseases Model With A Two-Lag Delay Differential Equation [PDF]

, 2018
We are concerned with the stability analysis of equilibrium solutions for a two-lag delay differential equation which models the spread of vector-borne diseases, where the lags are incubation periods in humans and vectors.
