Neural Delay Differential Equations

open access: yesCoRR, 2021
Neural Ordinary Differential Equations (NODEs), a framework of continuous-depth neural networks, have been widely applied, showing exceptional efficacy in coping with some representative datasets. Recently, an augmented framework has been successfully developed for conquering some limitations emergent in application of the original framework.

Distributed Delay Differential Equation Representations of Cyclic Differential Equations [PDF]

open access: yesSIAM Journal on Applied Mathematics, 2021
Compartmental ordinary differential equation (ODE) models are used extensively in mathematical biology. When transit between compartments occurs at a constant rate, the well-known linear chain trick can be used to show that the ODE model is equivalent to an Erlang distributed delay differential equation (DDE).

Accurate Solution for the Pantograph Delay Differential Equation via Laplace Transform

open access: yesMathematics, 2023
The Pantograph equation is a fundamental mathematical model in the field of delay differential equations. A special case of the Pantograph equation is well known as the Ambartsumian delay equation which has a particular application in Astrophysics.

Application of Legendre spectral-collocation method to delay differential and stochastic delay differential equation

open access: yesAIP Advances, 2018
Explicit solutions to delay differential equation (DDE) and stochastic delay differential equation (SDDE) can rarely be obtained, therefore numerical methods are adopted to solve these DDE and SDDE.

Properties of the third order trinomial functional differential equations

open access: yesElectronic Journal of Qualitative Theory of Differential Equations, 2015
The purpose of the paper is to study asymptotic properties of the third-order delay differential equation \begin{equation*} {\left(r_2(t)\left(r_1(t)\left(y'(t)\right)^\gamma\right)'\right)'}+p(t){\left(y'(t)\right)^\gamma}+q(t)f\left(y\left(\tau(t ...
