Web24 mrt. 2015 · This paper presents new finite difference schemes for solving the Helmholtz equation in the polar and spherical coordinates. The most important result presented in this study is that the developed difference schemes are pollution free, and their convergence orders are independent of the wave number k . Webequation follows directly from the H–J equation and the dynamical postulate of the path integral formulation and, secondly, to review Schr¨odinger’s own derivations of both the time-independent and time-dependent quantum wave equations. In order to do this in a comprehensible manner some related topics are briefly described in sections 5–7.
