A Fourier Series Method for the Numerical Solution of a Class of Parabolic Partial Differential Equations* A Fourier series method is described which, when applied to a certain class of parabolic partial differential equations, reduces the problem to a system of ordinary differential equations. An application is given for which the method shows a considerable advantage over conventional finite difference methods. CACM March, 1964 Forrington, C. V. D.
