# Albedo method

From Encyclopedia of Mathematics

*(in transport theory)*

A method of solving boundary value problems for a transport equation. The Albedo method is a variant of the matrix factorization method, the role of factorization coefficients being played by the matrices of reflection and transmission of a sequence of layers of increasing thickness. Practically speaking, the Albedo method is used only in problems in one-dimensional spaces, both to find the reflection and transmission coefficients and to find the solution of the transport equation in a medium.
