There are, however, a vast range of problems which are amenable to a computational approach. This book provides a concise, self-contained introduction to the basic numerical and analytic techniques, which form the foundations of the algorithms commonly employed to give a quantitative description of systems of genuine physical interest. The methods developed are applied to representative problems from classical and quantum physicsPPN: PPN: 1755157126Package identifier: Produktsigel: BSZ-4-NLEBK-KAUB | ZDB-4-NLEBK
