Introduction to the LAPW Method
The LAPW method is fundamentally a modification to the augmented planewave method of Slater (1937, 1964). Thus, before embarking on an exposition of the LAPW method, we review the relevant aspects of the APW method and the motivation for its modification to the LAPW method. Further details about the APW method may be found in the book by Loucks (1967), which also reprints several early papers that develop and use this method.
