## Abstract A wide‐angle finite‐difference beam propagation method for the solution of coupled nonlinear wave equations is introduced in this paper. The formalism is expanded in terms of Padé approximants for the Crank–Nicolson scheme. An iterative algorithm is utilized to optimize convergence in t

In previous papers the convergence of sequences of ``rectangular'' multivariate Pade -type approximants was studied. In other publications definitions of ``triangular'' multivariate Pade -type approximants were given. We extend these results to the general order definition where the choice of the de

We investigate the polynomials P n , Q m , and R s , having degrees n, m, and s, respectively, with P n monic, that solve the approximation problem We give a connection between the coefficients of each of the polynomials P n , Q m , and R s and certain hypergeometric functions, which leads to a sim
