Limiting absorption principle
ID: limiting-absorption-principle
The Limiting Absorption Principle (LAP) is a concept in the field of mathematical physics, particularly in the study of differential operators and partial differential equations. It relates to the analysis of the resolvent of an operator, which is a tool used to understand the behavior of solutions to differential equations. The LAP states that, under certain conditions, the resolvent operator of a differential operator can be defined and its limit can be taken as a parameter approaches the continuous spectrum.
