The Milne problem and higher orders of the WKBJ approximation
Solov'ev E. A.
A linear third-order equation, which is equivalent to the Milne equation, is derived. This equation is used to formulate a new version of the WKBJ approximation, in which the expansion has an extremely simple structure. A condition for the applicability for the higher-order corrections of the WKBJ expansion is found.
