On quadrature rules for solving Partial Differential Equations using Neural Networks

open access: yesComputer Methods in Applied Mechanics and Engineering, 2022
Neural Networks have been widely used to solve Partial Differential Equations. These methods require to approximate definite integrals using quadrature rules. Here, we illustrate via 1D numerical examples the quadrature problems that may arise in these applications and propose different alternatives to overcome them, namely: Monte Carlo methods ...

Exponential Quadrature Rules for Linear Fractional Differential Equations [PDF]

open access: yesMediterranean Journal of Mathematics, 2014
This paper focuses on the numerical solution of initial value problems for fractional differential equations of linear type. The approach we propose grounds on expressing the solution in terms of some integral weighted by a generalized Mittag-Leffler function. Then suitable quadrature rules are devised and order conditions of algebraic type are derived.
