Numerical Modeling of a Boundary Value Problem for a Singularly Perturbed Differential Equation with Two Boundary Layers Using the Spectral-Grid Method

This paper proposes a spectral-grid method based on Chebyshev polynomials of the first kind for the numerical solution of second-order singularly perturbed boundary value problems containing two boundary layers. The proposed method possesses several important advantages, includin...
