Abstract
We present a boundary element method for computing numerical solutions of the reaction‐diffusion telegraph equation in unbounded domains. This technique does not need artificial boundary conditions at the computational domain and uses a new algorithm to compute the Fourier transform, the convolution theorem, and the fact that the exact solution of the telegraph equation can be written as an integral transform in terms of the fundamental solution. We use the logistic growth model to find how the population of an organism evolves according to its growth rate. © 2014 Wiley Periodicals, Inc. Numer Methods Partial Differential Eq 31: 326–335, 2015
