Abstract:The Tau method is a highly accurate technique that approximates differential equations efficiently. This paper discusses two approaches of the Tau Method: recursive and spectral. In the recursive Tau, the approximate solution of the differential equation is obtained in terms of a special polynomial basis called canonical polynomials. The present paper extends this concept to the multivariate canonical polynomial vectors and proposes a self starting algorithm to generate those vectors. In the spectral Tau, the … Show more
