In this paper, we prove the global existence and exponential energy decay results of a coupled Lamé system with distributed time delay, nonlinear source term, and without memory term by using the Faedo–Galerkin method.

Solve High-Dimensional Reflected Partial Differential Equations by Neural Network Method
Reflected partial differential equations (PDEs) have important applications in financial mathematics, stochastic control, physics, and engineering. This paper aims to present a numerical method for solving high-dimensional reflected PDEs.

ANN-based methods for solving partial differential equations: a survey
Traditionally, partial differential equation (PDE) problems are solved numerically through a discretization process. Iterative methods are then used to determine the algebraic system generated by this process. Recently, scientists have emerged artificial

The authors describe a new methodology for solving systems of partial differential equations. They explain the methodology in the case of two- dimensional second-order linear elliptic problems of the form \(L_ i{\mathbf u}_ i = f_ i \text{ for }(x, y) \in D_ i\), \(M_ i{\mathbf u}_ i = g_ i \text{ for }(x, y) \in \partial D_ i\), \(i=1,2,...,m\), where

Asymptotic analysis of the biharmonic Schrödinger equation with fractional damping
In this paper, we study the decay behavior of solutions to the biharmonic Schrödinger equation under the effect of internal fractional damping. By employing semigroup theory and energy methods, we establish well-posedness results and investigate the long-

PDE-PRESERVING PROPERTIES [PDF]
A continuous linear operator \(T\) on the space of entire functions in \(d\) variables is called PDE-preserving for a given set \(\mathbb{P}\subseteq\mathbb{C}[\xi_1,\ldots,\xi_d]\) of polynomials if \(T\ker P(D)\subseteq P(D)\) for all \(P\in\mathbb P\), where \(P(D)\) is the differential operator obtained by replacing each variable \(\xi_j\) by ...

Based on the first author's construction of hyperreal numbers and hyperfunctionals [Lect. Notes Pure Appl. Math. 238, 81--117, Dekker, New York (2004; Zbl 1094.46508)]. The present paper investigates solvability of linear first order Cauchy problems in a similar setting of generalized functions, the space of extrafunctions.
