What is … an averaging principle?
This page hosts information on Carsten Hartmann's talk "What is … an averaging principle?" at the WhatIsSeminar.Abstract
The talk gives a high-level overview of problems that involve dynamical systems with slow and fast time scales. Prominent examples are the sun-earth-moon system in celestial mechanics or climate models in which the weather appears as a fast perturbation to the slowly varying climate. I will explain how the fast dynamics can be systematically eliminated from the equations of motion (averaging) thereby yielding closed-form equations that govern the motion the slow variables.
