  journal={arXiv: Mathematical Physics},
The Green's function method which has been originally proposed for linear systems has several extensions to the case of nonlinear equations. A recent extension has been proposed to deal with certain applications in quantum field theory. The general solution of second order nonlinear differential equations is represented in terms of a so-called short time expansion. The first term of the expansion has been shown to be an efficient approximation of the solution for small values of the state…

Neural Green's function for Laplacian systems



New Green's functions for some nonlinear oscillating systems and related PDEs.

During the past three decades, the advantageous concept of the Green's function has been extended from linear systems to nonlinear ones. At that, there exist a rigorous and an approximate extensions.

Nonlinear implicit Green’s functions for numerical approximation of partial differential equations: Generalized Burgers’ equation and nonlinear wave equation with damping

A representation formula for second-order nonhomogeneous nonlinear ordinary differential equations (ODEs) has been recently constructed by M. Frasca using its Green’s function, i.e. the solution of

Representation of the Green's function for nonlinear differential equations

In this paper we study some classes of nonlinear second order ordinary differential equations allowing a specific representation for the Green's function. In particular, we show that if the nonlinear


We show that Green function methods can be straightforwardly applied to nonlinear equations appearing as the leading order of a short time expansion. Higher-order corrections can be then computed

Green’s function approach in approximate controllability for nonlinear physical processes

The aim of this study was to investigate the bifurcations and attractors of the nonlinear dynamics model of the saccadic system, in order to obtain a classification of the simulated oculomotor behaviours.

Duals and propagators: A canonical formalism for nonlinear equations

A new formalism for solving general nonlinear equations is proposed. Given a nonlinear operator equation, a dual operator is constructed, canonically, similar to the adjoint operator in linear

Propagators for non-linear systems

A canonical formalism based on forward and backward propagators is developed for problems described by systems of general non-linear equations. These propagators are shown to yield the problem's
