Ordinary Differential Equations [PDF]

open access: yes, 2021
AbstractIn this chapter, we discuss a first application of the time derivative operator constructed in the previous chapter. More precisely, we analyse well-posedness of ordinary differential equations and will at the same time provide a Hilbert space proof of the classical Picard–Lindelöf theorem (There are different notions for this theorem.

nmODE: neural memory ordinary differential equation

open access: yesArtificial Intelligence Review, 2023
Brain neural networks are regarded as dynamical systems in neural science, in which memories are interpreted as attractors of the systems. Mathematically, ordinary differential equations (ODEs) can be utilized to describe dynamical systems.

Neural ordinary differential equation and holographic quantum chromodynamics [PDF]

open access: yesMachine Learning: Science and Technology, 2020
The neural ordinary differential equation (neural ODE) is a novel machine learning architecture whose weights are smooth functions of the continuous depth. We apply the neural ODE to holographic QCD by regarding the weight functions as a bulk metric, and

Uniqueness criteria for ordinary differential equations with a generalized transversality condition at the initial condition

open access: yesElectronic Journal of Qualitative Theory of Differential Equations, 2022
In this paper, we present some uniqueness results for systems of ordinary differential equations. All of them are linked by a weak transversality condition at the initial condition, which generalizes those in the previous literature. Several examples are

Gluon dynamics from an ordinary differential equation

open access: yesEuropean Physical Journal C: Particles and Fields, 2021
We present a novel method for computing the nonperturbative kinetic term of the gluon propagator from an ordinary differential equation, whose derivation hinges on the central hypothesis that the regular part of the three-gluon vertex and the ...

Linearisation of a second-order nonlinear ordinary differential equation

open access: yesActa Polytechnica, 2023
We analyse nonlinear second-order differential equations in terms of algebraic properties by reducing a nonlinear partial differential equation to a nonlinear second-order ordinary differential equation via the point symmetry f(v)∂v.
