Explicit Finite Difference Methods for the Delay Pseudoparabolic Equations [PDF]
The Scientific World Journal, 2014 Finite difference technique is applied to numerical solution of the initial-boundary value problem for the semilinear delay Sobolev or pseudoparabolic equation. By the method of integral identities two-level difference scheme is constructed. For the time

Finite Difference Methods for Option Pricing under Lévy Processes: Wiener-Hopf Factorization Approach [PDF]
The Scientific World Journal, 2013 In the paper, we consider the problem of pricing options in wide classes of Lévy processes. We propose a general approach to the numerical methods based on a finite difference approximation for the generalized Black-Scholes equation.

Finite-difference methods for solving 1D Poisson problem
Discrete and Continuous Models and Applied Computational Science, 2022 The paper discusses the formulation and analysis of methods for solving the one-dimensional Poisson equation based on finite-difference approximations - an important and very useful tool for the numerical study of differential equations. In fact, this is

The Finite Difference Methods for φ4 Klein-Gordon Equation [PDF]
Al-Rafidain Journal of Computer Sciences and Mathematics, 2008 We solved φ4 Klein-Gordon equation numerically by using two finite difference methods: The first is the explicit method and the second is the implicit (Crank-Nicholson) method.

IET Microwaves, Antennas & Propagation, 2023 A stochastic contour path finite‐difference time‐domain (S‐CP‐FDTD) algorithm is presented for electromagnetic wave propagation in metallic enclosures with uncertain slot size. The correlation coefficient between the field and size of slot was set to one.
