We investigate the resolution of parabolic PDEs via Extreme Learning Machine (ELMs) Neural Networks, which have a single hidden layer and can be trained at a modest computational cost as compared with Deep Learning Neural Networks. Our approach addresses the time evolution by applying classical ODEs techniques and uses ELM-based collocation for solving the resulting stationary elliptic problems. In this framework, the θ-method and Backward Difference Formulae (BDF) techniques are investigated…

Exponential Convergence of Deep Operator Networks for Elliptic Partial Differential Equations

It is proved that the neural networks in the ONet have sizeO(|log(ε)|) for some κ > 0 depending on the physical space dimension, which follows from classical elliptic regularity.

An almost L‐stable BDF‐type method for the numerical solution of stiff ODEs arising from the method of lines

A new BDF‐type scheme is proposed for the numerical integration of the system of ordinary differential equations that arises in the Method of Lines solution of time‐dependent partial differential equations, which is almost L‐stable and of algebraic order three.

Numerical Models for Differential Problems

This text considers the classical elliptic, parabolic and hyperbolic linear equations, but also the diffusion, transport, and Navier-Stokes equations, as well as equations representing conservation laws, saddle-point problems and optimal control problems.
